Ajax have finally filled the void left by Marc Overmars with the appointment of former Arsenal and Borussia Dortmund transfer chief Sven Mislintat.

Overmars was sacked by Ajax in February 2022 after "a series of inappropriate messages sent to several female colleagues over an extended period of time".

The former Netherlands international apologised for his actions but departed the club, accepting a role at Belgian side Antwerp a month later.

In the meantime, Ajax have operated without a specific director of football, Overmars' duties instead handled by technical managers Gerry Hamstra and Klaas-Jan Huntelaar.

Mislintat, who left Stuttgart in late 2022, will step into the void from May 19.

Ajax CEO Edwin van der Sar said of the appointment: "It is good for Ajax that we have been able to fill this important position with an internationally experienced football director who can start quickly.

"A careful process preceded the search for the right person. We were looking for someone who stands for attacking and attractive football.

"Someone who has an international network, and has an eye for scouting, development, and the growth of our own youth.

"Sven meets the profile, and he made a very good impression on us from the first talks in February.

"In addition, he has a way of working that fits today's industry. I am convinced that he will make an important contribution to new successes of Ajax."

Mislintat made his name at Borussia Dortmund, where he was head of scouting and head of professional football between 2006 and 2017, playing a vital role in the identification of talents who re-established BVB among the elite.

Robert Lewandowski, Pierre-Emerick Aubameyang, Mats Hummels, Shinji Kagawa and Ousmane Dembele all signed for Dortmund on Mislintat's watch.

He became Arsenal's head of recruitment in 2017 but his spell in charge of transfers was largely deemed a disappointment, leaving in February 2019.

Mislintat returned to Germany with Stuttgart two months later, staying until late last year when he opted against signing a new contract as he sought a new challenge.

Police arrested a young male on Sunday after Groningen defender Jetro Willems was punched by a fan of his own team during an Eredivisie derby against Heerenveen.

Former PSV and Newcastle United player Willems was attempting to calm the home supporters at pitchside as tensions ran high when he was attacked, with the shocking incident caught by TV cameras.

Groningen were trailing 2-0 at the time, going into the closing stages, and the game was briefly paused as referee Serdar Gozubuyuk took the players off the field.

They later returned to complete the match, with no further goals scored.

The local police force, Politie Groningen, announced on Twitter: "A minor-age boy has just been arrested in #Groningen on suspicion of beating a @fcgroningen player during the match in the Euroborg [stadium] this afternoon.

"Another man was also arrested during that match, also on suspicion of assault. Both arrested suspects have been transferred to the police station and will be interrogated there."

Ajax head coach John Heitinga rued more frustrations in a disappointing season after Feyenoord came from behind to strike a significant Eredivisie title blow.

Arne Slot's side moved six points clear at the Dutch top-flight summit after Lutsharel Geertruida scored an 86th-minute winner in a 3-2 victory over second-placed Ajax on Sunday.

It marked the first time since August 2014 that Ajax lost an Eredivisie game they had led at half-time, after Edson Alvarez and Dusan Tadic goals had sent the hosts in leading 2-1 at the interval.

With only the top two qualifying for the Champions League, Heitinga – in charge until the end of the season following Alfred Schreuder's sacking in January – acknowledged Ajax are struggling with AZ and PSV in hot pursuit.

"Let's be clear: this is not the season Ajax wants it to be," said former defender Heitinga, as quoted by De Telegraaf.

"I have been asked to help this club. When I started we were fifth and then we won seven league games in a row. 

"And we probably would have won here too if [Mohammed] Kudus scored in the final phase. But unfortunately, he didn't. We are really going to do everything we can to finish this season as high as possible."

Stats Perform's predictor, which calculates the probability of a team's league finish based on numerous data, suggests Feyenoord have a 92.6 per cent chance of winning the league after a late win over Ajax.

Those title hopes were boosted by Geertruida's header, which was Feyenoord's latest winner in De Klassieker since November 1969 when Theo van Duivenbode scored in the 87th minute.

Feyenoord coach Slot said his side can dare to dream of a first championship since 2017 and just a second this century.

"We are in very good shape," he said. "I dare say that we are competing for the championship. And that we are in a fantastic position too.

"We had a great victory here. We know how much effort it takes to win every time. There is nothing wrong with that; we like to do that.

"I saw a physical performance today that also appeals to the imagination. If we can keep delivering and no one gets injured, then we are in really good shape."

Slot's men were somewhat fortunate in the first half, though, as Quilindschy Hartman escaped a second caution in quick succession from referee Danny Makkelie.

The defender was promptly removed in the 25th minute for Marcos Lopez, with the game finely poised at 1-1 after Alvarez cancelled out Santiago Gimenez's early opener.

"He got away with it, the referee could have given yellow again," Slot told ESPN. "Although you also have to analyse that first yellow card. Three violations preceded that. 

"Everyone understands that you don't enjoy playing football anymore if you have committed an offence that could have been your second yellow card. 

"Then you can no longer play against Kudus, a man who is so incredibly good in terms of individual class."

Dutch defender Jetro Willems was punched by a fan of his own team in an Eredivisie game on Sunday after trouble broke out during Groningen's derby defeat against Heerenveen.

The 28-year-old Groningen player went over to an area of the ground where tensions were running high and attempted to calm the home supporters.

Instead, he ended up being struck by one fan who reached over others before taking a swing at Willems, with the shocking incident caught by TV cameras.

Groningen were trailing 2-0 at the time, going into the closing stages, and the game was briefly paused as referee Serdar Gozubuyuk took the players off the field.

They later returned to complete the match, with no further goals scored.

The incident could see Groningen face punishment, but former PSV and Newcastle United player Willems joked about it after the final whistle, telling Dutch ESPN: "I come from Rotterdam-Zuid; I can take a beating, right?"

He added: "I don't want to say too much about it. Everything gets blown up at some point. It is certainly not normal, but we will sit down with the club and then you will hear more later or tomorrow."

The game was played with an early kick-off, starting at 12:15 local time (11:15 GMT), with both goals coming before half-time from Sydney van Hooijdonk.

Groningen forward Elvis Manu reacted with horror to the assault, quoted by VI.nl as saying: "It's a pitch-black day. This must never happen.

"It's a great pity. One person ruined it for everyone. I think we had the crowd behind us from minute one. We have felt support.

"Too bad something like this happened. Everyone is very emotional, but this has no place on the football field."

Feyenoord head coach Arne Slot hailed the "unreal" clinical display from his side after thumping Shakhtar Donetsk 7-1 in their Europa League last-16 second leg.

Thursday's contest at De Kuip was far less evenly contested than last week's 1-1 draw, with Santiago Gimenez getting the ball rolling for the hosts inside nine minutes.

Orkun Kokcu scored twice before half-time and Oussama Idrissi likewise after the restart, before Alireza Jahanbakhsh and Danilo completed the rout by the 66th minute.

Kevin Kelsy pulled a goal back late on, but it was of no real consolation to the Ukrainian visitors as they bowed out of the competition.

It marks the second-biggest win for a Dutch side in a major European competition at this stage or beyond, after Ajax's 10-0 win over Omonia Nicosia in the 1979-80 European Cup.

Reflecting on a memorable result for his side, Slot said: "It was unreal how we put the match to bed so quickly.

"Normally we need more chances to score, so compliments to my players for being so efficient this evening.

"Shakhtar had a good spell in the first half, and you saw how our players blocked their shots in the box. They were so determined to get a good result."

Feyenoord are now unbeaten in 16 matches this calendar year, with their thumping victory against Shakhtar coming three days before facing fierce rivals Ajax.

Slot's side are three points better off than Ajax at the summit ahead of Sunday's Eredivisie showdown at the Johan Cruijff ArenA.

"Of course this victory helps for the duel with Ajax," Slot said. "This gives a lot of confidence. 

"But I also see that Ajax have regained the level they had at the start of the season. Ajax have a good team again."
