Seamus Coleman, Romelu Lukaku and Ross Barkley could all potentially leave Everton in the next January transfer window.

The trio were under linked with possible exits throughout the summer and subsequently stayed following the arrival of new manager Ronald Koeman.

Here, Football Insider explains why Everton could face a fresh battle to hang on to the three star men in the winter window.

Ross Barkley

Barkley has had an inconsistent start to the 2016-17 Premier League season and after once being dubbed England’s best young talent, he’s struggled to recapture that form.

The England youngster was substituted in Everton’s clash with Sunderland and left out of Gareth Southgate’s England squad after a string of poor performances at the start of the campaign.

Ronald Koeman called for improvements and while Barkley has upped his game slightly since, he’s looked a shadow of the player he was when he broke into the first team.

He could look to make a move this January as he looks uncomfortable in Everton’s midfield and may be in need of a new challenge.

Romelu Lukaku

The forward has been in sublime form for the Toffees in their opening seven fixtures and Lukaku has already netted five goals this season.

He’s got one of the best goal-scoring ratios in the league and only Diego Costa has been more deadly in front of goal during the new campaign.

The Belgian international was linked with a number of clubs throughout the summer including Chelsea and Juventus.

More recently, it’s been rumoured that Manchester United could be in for the star and given Mourinho’s title ambitions, it may be hard for Everton to stop Lukaku leaving.

Seamus Coleman

As well as Lukaku, Mourinho has reportedly sent scouts to watch Coleman and the Everton defender would be the perfect replacement for Matteo Darmian.

Manchester United have started the season with Antonio Valencia at right-back but with Darmian likely to make a return to the Serie A, Mourinho wants to bring in a new defender.

Coleman has performed well for Everton recently and the 28 year-old could relish the opportunity of joining a regular big four club.

In other Everton news, Manchester City forward Kevin De Bruyne could return for the clash against the Toffees which would be a blow for Koeman’s side.
