• Dewsbury-Hall: Maresca will surprise people at Chelsea

  Kiernan Dewsbury-Hall believes new Chelsea manager Enzo Maresca will "surprise a lot of people" when they watch the Blues this season.

  The Italian led Leicester City straight back to the Premier League as Championship winners in his only season in charge and succeeds Mauricio Pochettino at Stamford Bridge.

  The Foxes topped the second division table with 98 points, with Dewsbury-Hall a key figure in his squad as he netted 12 goals and provided 14 assists last season – his best tally in a single campaign.

  Dewsbury-Hall was also named Leicester's Player and Players' Player of the Year.

  The midfielder made the switch to West London earlier this month for £30million and is confident that Maresca will have Chelsea challenging for trophies in no time.

  "The manager was a big catalyst in wanting me to come," Dewsbury-Hall told BBC Sport.

  "I knew from Leicester, a club that went down and had a lot of problems, how he managed to galvanise that if everyone manages to buy into the system.

  "I genuinely think in a short space of time we can be pushing for minimum top four - but more than that.

  "He may be unknown for a lot of people, but he is top, top level. He will surprise a lot of people."

  Chelsea's pre-season got off to a frustrating start as they were held to a 2-2 draw by League One side Wrexham in Maresca's first game in charge on Wednesday.

  Dewsbury-Hall did not play in that match but is training with the squad in the United States and could feature in their next outing against Celtic on Saturday.

  The 25-year-old is confident the manager's tactics will come across soon, with the players buying into his style.

  "We've only been doing it for two or three weeks, but the combination plays are really quick and tidy," he added.

  "That's after two weeks. I remember he said to us at Leicester after six months or a year, there might be teething problems at the start, but it will improve.

  "Within the first week at Leicester, I was convinced this was top, top level. I felt a bit stupid; I thought I knew a lot about football, but he was teaching me things on a daily basis that I didn't really know before. He has an aura, he can be strict, or gentle and soft - he has both sides.

  "I am getting the same feedback here with the lads. They've bought into it here from minute one which is exciting. With a system and philosophy, you need everyone to buy in because, if they do, you can really achieve something."

• Norris 'not comfortable' despite setting pace in Belgium practice

  Lando Norris admitted he was "not comfortable" despite being fastest in the Belgian Grand Prix second practice.

  McLaren finished first and second on Friday, with Norris finishing just 0.215 seconds ahead of team-mate Oscar Piastri.

  Max Verstappen finished third, but despite an impressive performance, his 10-place grid penalty will affect his result.

  Norris finished second in the Hungarian Grand Prix last week, behind Piastri, in a race overshadowed by a radio spat between the Brit and the pit wall.

  Having put that behind him, even after a confident practice session on Friday, Norris is not willing to rest on his laurels with Red Bull showing their threat.

  "Red Bull are very quick at the minute," Norris said. "So, tricky, but I've just not felt very comfortable today with the car.

  "So hopefully I just wake up [on Saturday] and feel a bit more comfortable with it. But we'll try and improve a few things and see again.

  "I know it looked good on the timesheets, but I've not felt super comfortable in just going out and doing it. So, hopefully, I can just get in a bit more of a rhythm and feel a bit better out there."

  Meanwhile, Lewis Hamilton finished in 10th after struggling to match the pace set in the second session.

  Mercedes have been credited for their improvement in recent weeks, with Hamilton winning at Silverstone before finishing third at Hungaroring last Sunday.

  However, he was also left disappointed on Friday and said he was hoping for the forecast rain over the rest of the weekend to give the team more of an edge.

  "It was a pretty bad day," Hamilton said.

  "I don't really know what to say! Obviously, it's been feeling great in the past couple of races, but it just felt completely different today.

  "We worked on it. The first session was not great, but then in the second session we made some changes, and it started off great, and then when I got to the soft tyre I just couldn't improve and there were a bunch of balance issues we had through the lap.

  "It was better through this session, but everyone else went even better. So, to be 1.2s behind is not great.

  "If it rains, then that opens it up a little bit and, hopefully, we can do a better job. I think the car should be better in the wet than it is in the dry."

• “The favourite is Thompson”-Boldon highlights Jamaican champion as man to beat in 100m in Paris

  Trinidadian four-time Olympic medallist Ato Boldon has named Jamaican sprinting sensation Kishane Thompson as his favourite to take 100m gold at the Olympic Games in Paris.

  Thompson, 23, is currently the world leader in the event after running a personal best 9.77 to win the 100m title at the JAAA/Puma National Senior Championships at the National Stadium in Kingston in June.

  The MVP Track Club-trained sprinter also produced times of 9.82 and 9.84 in the heats and semi-finals, respectively, at those national championships and, most recently, ran 9.91 shutting down to win at the Gyulai Istvan Memorial in Hungary on July 9.

  “Thompson is the favourite,” Boldon said in an interview with LetsRundotcom on YouTube on Friday.

  “I know Noah (Lyles) is the World champion. I think Noah made it a little bit more interesting by running that 9.81 into a headwind which kind of almost converts to a 9.77 but there’s no way you can look at the way in which Thompson ran that 9.77 and just go ‘Oh Noah will beat him.’ Noah has his hands full with that guy,” Boldon said.

  Blazing speed acknowledged, one thing that Thompson lacks that his other competitors don’t is experience competing at the highest level of the sport with this being his first time representing Jamaica at any level.

  If there is anything to prevent Thompson from delivering on the form that he’s shown so far this season, Boldon believes that would be this lack of experience on a stage like the Olympic Games compared to his peers.

  “There are things which I see people completely ignoring. Kishane Thompson has not been under the microscope of Olympic favourite. Rounds are a great equalizer. Noah has the medals that he does because of how well he runs rounds. Is Noah suddenly a lock for the silver? No but he does have his hands full,” he said.

  “There are others who are going to be in the 100m that are used to the pressure and pressure is a big thing. If he’s able to pull this off, you write books about stuff like that,” he added.

   Thompson's quest for Olympic glory will begin in the heats of the men's 100m beginning on Saturday' August 3.
