Simone Inzaghi urged Inter to build on their strong performance against Napoli after ending the Serie A leaders' unbeaten start to the campaign.

Piotr Zielinski netted Napoli's first away goal in four league games against the Nerazzurri to open the scoring with their first strike at San Siro since April 2017.

However, Hakan Calhanoglu equalised from the spot before teeing up Ivan Perisic's header to put Inter 2-1 up at half-time, the Turkey international recording at least a goal and an assist in a Serie A match for the 10th time since his debut in 2017-18.

Lautaro Martinez seemed to have put the game out of Napoli's reach, though substitute Dries Mertens' pulled one back to overtake Antonio Vojak as the club's leading scorer in the Italian top flight with his 103rd goal.

The defending champions managed to hang on to end Napoli's 21-game unbeaten league run, taking them within four points of the top two, and Inzaghi wants more from his side ahead of a crucial Champions League clash with Shakhtar Donetsk on Wednesday.

"It was a key game for the season, although the most important one will be in three days' time," Inzaghi told DAZN.

"We beat a very strong Napoli side and we did it deservedly too. It's always going to be a struggle against Napoli, especially as they have on average the highest possession statistics in Serie A this season with 60 per cent.

"We must continue like this. We've got to focus on the Champions League next because it's been too many years that Inter haven't got past the group phase and we have a big opportunity to achieve it.

"Wednesday we have a great chance, we have some injuries but it's a moment like this for everyone. We have to move forward match after match. We have left some points because the Champions League is very important for us."

Inter had Samir Handanovic to thank for the three points after his stoppage-time save against Mario Rui in which he tipped onto the crossbar from the left-back's header at the back post.

Mertens then blasted over during a chaotic eight minutes of additional time and Inzaghi admitted he was concerned in the closing stages while explaining why Calhanoglu got to take the first-half penalty.

"We had been a whisker away from winning several of the other head-to-head clashes, so a little fear was inevitable towards the end during eight minutes of stoppages," he added.

"We had tests in training, Perisic, Calhanoglu and Lautaro took three penalties each and scored all three, so I said just decide between yourselves! Hakan is in great shape at the moment and I wouldn't have taken him off if he wasn't on a yellow card today."

Youri Tielemans has identified what makes absent Belgium teammate Kevin De Bruyne such a "special player" ahead of their Euro 2020 quarterfinal against Italy on Friday.

Belgium head coach Roberto Martinez declared that Manchester City midfielder De Bruyne will miss the quarter after sustaining an ankle knock in their last-16 win over Portugal. De Bruyne was also absent from training on Wednesday.

De Bruyne, who missed Belgium's opening 3-0 win over Russia with a facial injury, has scored one goal and provided two assists during Euro 2020, helping the Red Devils win all four games, meaning Martinez has a difficult job replacing him.

"Kevin is a special player because in my opinion, he always makes the right decision, even if you think he misplaces a pass, it’s not," Tielemans said during a news conference ahead of the quarterfinals.

"Always does something in his mind, always makes the right decision, very efficient, has a lot of assists or goals, that helps our team a lot."

He added: "As a team we have to create more options on the ball, move more, and make the right choices.

"Maybe we were under pressure a little bit, second half against Portugal, they had a lot of offensive options on the pitch, made it difficult for us to get out of there, as a team we have to find those solutions."

De Bruyne was replaced early in the second half against Portugal due to injury, before Belgium survived a barrage of pressure, with the 2016 European champions ending with 23-6 shots.

Belgium, who finished third at the 2018 World Cup and lost in the quarters at the 2016 Euros, ground out the win in a sign of maturity according to Tielemans.

"We learnt lessons from 2018, we’re more realistic, we play nice football, certain matches we have a lot of possession, create chances," the Leicester City midfielder said.

"Like you saw against Portugal there’s moments you have to suffer as a team, you might not get many opportunities, you have to score them, that’s where we learned from Russia, to be efficient, decisive in the right moment, when we have an opportunity to score we remember that from 2018."

Forward Dries Mertens is one candidate to come into the Belgium XI to replace De Bruyne against Italy, having replaced him against Portugal.

Mertens plays his club football with Napoli in Serie A, and added that quarterfinal opponents Italy appeared full of confidence.

"I’ve seen they have a lot more confidence now, they’ve played many matches and won a lot without giving goals away," he said.

"It gives confidence, experienced players but also young players, the way they celebrate when they win, many people didn’t expect that, it gives them a lot of confidence."

The 34-year-old also added there was no thought about Euro 2020 being his or this generation of Belgian players' last chance to win a trophy.

"No, not really," he said. "We do need to be realistic, realise we’re here now, we have a chance, you don’t get chances with a national team to win, every two years you have one chance to win one trophy, its very little.

"We’ve been doing well for a few years now, this is a chance we need to take, we have great facilities, we have great staff, people who know where we want to go.

"Those are important moments, I believe in the future of the Belgium team. This is a chance we have to take."
