Assessing 10 players who made Premier League debuts last weekend

The opening round of Premier League matches is complete. ESPN FC assesses the maiden performances of 10 players making their debuts in English football's top division.

Sead Kolasinac | 24 | Defender | Arsenal

The defender is already a cult hero at the Emirates, and that's because of his willingness to charge forward and join attacks. During Friday's spectacular 4-3 defeat of Leicester there were regular sights of him on the rampage, though, like the rest of Arsenal's defence, he was guilty of mistakes, including allowing Shinji Okazaki to nod in the Foxes' first equaliser and then Jamie Vardy for their second. Rating: 6/10

Alexandre Lacazette | 26 | Forward | Arsenal

Beginnings barely get brighter than scoring just 96 seconds into a home debut, which Lacazette achieved with a smartly directed header from Mohamed Elneny's chipped cross, and the Frenchman remained a threat throughout the seven-goal thriller. A late solo run and shot produced a fine save from Kasper Schmeichel. Rating: 7/10

Ahmed Hegazy | 26 | Defender | West Brom

No manager appreciates centre-backs like Tony Pulis, and scoring the winning goal in a 1-0 win certainly helps. Against Bournemouth, the Egyptian crashed in a header after Chris Brunt's cross, and held firm in defence, meaning the Baggies did not suffer for the absences of Jonny Evans and Gareth McAuley. Rating: 8/10

Antonio Rudiger | 24 | Defender | Chelsea

It can't have helped to have defensive partner Gary Cahill dismissed after 14 minutes, an incident that ended fellow debutant Jeremie Boga's day after just 18 minutes, but Rudiger wilted under the pressure of Burnley's forceful style in a 3-2 defeat. He may well have looked decent going forward, but Saturday was a real day to forget for the German. Rating: 4/10

Alvaro Morata | 24 | Forward | Chelsea

He began his Saturday afternoon on the bench for Chelsea, but came on for the last 30 minutes to try and rescue a lost cause. It took him 10 minutes to score, and he also supplied the assist for David Luiz's late goal. Amid the wreckage of an afternoon that was seriously damaging to the defending champions, Morata was cause for solace; he had been his team's best player. Rating: 8/10

Davy Klaassen | 24 | Midfielder | Everton

The headlines went to Wayne Rooney's scoring return in Saturday's 1-0 win over Stoke City, but eyes were also on the former Ajax midfield general. And Klaassen only lasted an hour at Goodison Park, where he rather struggled with the pace of the game and in finding his passing targets, and was replaced by the far more athletic Tom Davies. Rating: 5/10

Steve Mounie | 22 | Forward | Huddersfield Town

He scored two goals in Huddersfield's dream start as a Premier League club, a 3-0 win at Crystal Palace, and it looks as if David Wagner has signed a real gem in the £11.5 million Benin striker. Leaden-footed Palace struggled to cope with his power and pace. His first goal was a bullet header, the second a sharply hit snap shot. Rating: 9/10

Danilo | 26 | Defender | Manchester City

The former Real Madrid full-back is heavily right-footed, but was fielded as a left wing-back by Pep Guardiola at Brighton. He looked lively in the attack, when repeatedly looking to cut inside, but was a little more shaky in his defensive duties. It took Brighton 45 minutes to get into the game, so dominant were City, but it was noticeable that their best attacks came down Danilo's flank. Rating: 6/10

Ederson | 23 | Goalkeeper | Manchester City

A clean sheet and a couple of saves at Brighton in City's 2-0 win made it a comfortable enough start for the world's most expensive goalkeeper. He certainly looked a little more secure than Claudio Bravo did last season, but there were a couple of moments of concern. Danilo had to bail Ederson out at one point after he committed too late to a Markus Suttner cross, and the Brazilian looked rather panicky on those occasions when Brighton pumped the ball into the box. Rating: 6/10

Kyle Walker-Peters | 20 | Defender | Tottenham Hotspur

Not a new signing as such, but a Premier League debutant nonetheless, Walker-Peters played at right-back for Spurs at Newcastle, filling the role vacated by near-namesake Kyle Walker's move to Manchester City, and Kieran Trippier's untimely injury. And against a not particularly adventurous Newcastle, the 20-year-old acquitted himself well and looks another gem from Spurs' production line. Rating: 7/10
