He has made 32 appearances this season, in which Arsenal have kept 10 clean sheets. He has also weighed in with a couple of goals and an assist.

However, he arrived having made just nine appearances previously in 2019 following a double hernia operation and has managed just 11 in all competitions for Arsenal since, providing two assists.

Mings put his injury woes behind him and impressed on loan in Villa’s promotion campaign last season from the Championship. In need of heavy recruitment, Mings was top of boss Dean Smith's shopping list.

As you would imagine, he has been a mainstay of Villa’s defence this season, making 26 appearances, in which he has contributed two goals and an assist. Villa have kept three clean sheets in the games he has played.

Wesley was meant to be the man to fire Villa to Premier League safety, arriving after a season in which he'd scored 17 goals in Belgium.

Villa thought they'd found their new Christian Benteke when he netted four times in his first eight Premier League games, but he then went 12 league games with a goal. Frustratingly for him and the club he suffered a season-ending injury in the same game in which he broke his scoring duck, at Burnley in January.

Danish midfielder Billing was one of the few bright sparks during an otherwise miserable 2018-19 season for Huddersfield, who were relegated to the Championship. Too good for the second tier, it was inevitable he would be in a top-flight league this season, with Bournemouth picking him up for £15m.

“An exciting step forward” was how Billing described the move at the time, one which has so far brought three goals and an assist from 29 appearances.

One of the stars of Derby’s run to last season’s play-off final, which saw him contribute 15 goals and three assists in 40 Championship appearances. Despite playing in a number of pre-season games for Liverpool at the start of this season, the Reds felt his development was best served on loan at Bournemouth.

Six goals for the struggling Cherries have followed, in 23 appearances. He also has two assists from two FA Cup ties.

One of the Championship's best strikers in 2018-19, Maupay left Brentford, for whom he had scored 41 goals in 95 games, to join Albion for £16m. "His record in the Championship has been exceptional and now his challenge is to transfer that to the Premier League,” boss Graham Potter said at the time.

His response to this challenge has been eight goals in 28 Premier League games, including a run of three in three during an unbeaten three-game run at the start of December.

Midfielder Trossard signed a four-year deal after joining from Genk, with whom he had won the Belgian league the season before. An “attack-minded player” who “brings good experience” was how Seagulls boss Graham Potter described the player.

An early-season groin injury didn’t help him, but he has been in and out of the Albion side this season, scoring three times and assisting four goals in 23 appearances.

Brighton broke their club record to bring in centre-back Webster, who had helped Bristol City finish eighth in the Championship in 2018-19. "He is a quality defender, comfortable on the ball and fits the profile of the player we want to bring to the club," said Brighton boss Graham Potter.

He has been a regular in a side that has changed its style this season to play out more from the back, making 23 appearances, helping them keep four cleansheets in those.

Seven years after departing for Southampton, striker Jay Rodriguez returned to hometown club Burnley to boost their attacking numbers. In his time away, he claimed 35 goals in 126 games for Southampton, earning his only England cap against Chile in November 2013, before scoring 33 in 89 games for West Brom.

More often used as a substitute in the first half of the season, he has become a regular following an injury to Ashley Barnes and has eight goals and one assist so far this season, from 31 games.

Signed permanently this summer by Chelsea, midfielder Kovacic is actually in his second season at the Blues following a loan spell last campaign.

Regularly switched with Ross Barkley by Maurizio Sarri, Kovacic made 32 Premier League appearances for Chelsea last season and has followed that up with 37 in all competitions this campaign, during which he has scored twice and assisted three goals.

Another player who made a loan move permanent. Forward Ayew spent 2018-19 on loan at Palace from Swansea, during which he scored twice in 25 appearances and "played his part in the club securing its highest Premier League points tally in the last campaign" according to boss Roy Hodgson.

He has bettered that goals tally this season, scoring eight times in 30 matches, including two in his last two league games before the season was halted.

Experienced former England centre-back Cahill moved to Sehurst Park in the summer having spent seven years with Chelsea that saw him win eight major honours. "I'm hungry to prolong my career as long as I possibly can - I feel like I'm in great shape whoever I play for,” he said.

He has made 22 appearances so far, 20 of them coming in the Premier League, during which Palace have kept six cleansheets, including three on the bounce in the three games prior to the season halting.

After six seasons at Everton, during which he made 133 appearances but suffered his share of injuries, Republic of Ireland midfielder James McCarthy joined Crystal Palace this summer. "He's suffered some setbacks with injury in recent years, and I genuinely believe Palace is a great place for him to restart his career,” said Palace chairman Steve Parish.

He figured rarely in the first half of this season, but has established himself as a regular since Christmas. In total, he has made 26 appearances.

Decorated England midfielder Delph made the move to Everton this summer after a successful spell at Manchester City, where he won two Premier League titles. Delph played 22 times in City's Premier League-winning season of 2017-18 but had seen his first-team chances limited since.

He has been in and out of the Toffees side this season, partly because of injury, but has made 20 appearances in all competitions, under three different managers.

Forward Iwobi came through the ranks at Arsenal, scoring 15 goals in 149 games before moving to Everton this summer. "Alex was one of our main targets for this window and I believe he is a fantastic signing. He is a direct and skilful winger and attacking midfielder who always works very hard," then Everton manager Marco Silva said.

He has scored twice and assisted a further goal so far in 22 appearances for the Toffees in a campaign that was briefly halted by injury just after Christmas.

It would be fair too say that Kean's debut season has not quite gone as well as he or Everton would have hoped. Regarded as one of Europe's most exciting young strikers, he arrived having scored eight times in 21 games for Juventus and two in three for Italy.

Still young, there is plenty of time yet beyond this campaign, but so far he has just one goal and two assists in 26 appearances, the vast majority of which have been off the bench.

You know what you get with Perez. Five years at Newcastle prior to his summer switch to the King Power demonstrated that he can be red hot in bursts but go missing for long periods.

Quick, skilful, with an eye for goal, he has somewhat lived up to his billing, providing five assists and seven goals, three of which came in that stunning 9-0 demolition of Southampton.
