Raheem Sterling fears he will play no further role at Chelsea after his surprise omission from the squad against Manchester City. The forward’s status has been further diminished by the club agreeing to sign João Félix from Atlético Madrid for €50m (£42m) plus €10m (£8.5m) in potential add-ons. Sterling, who has three years left on a deal worth £325,000 a week, is urgently seeking clarity from the club over his future at the club after Enzo Maresca took the “technical decision” to leave him out of his side’s 2-0 defeat against City on Sunday. Chelsea’s head coach had already given Sterling an indication of his diminished status by ­telling the 29-year-old winger during a conversation at the end of last week to consider his future before the transfer window shuts. Maresca has plenty of options in wide areas and has made it clear he wants to decrease the size of a squad containing more than 30 players. Félix had an underwhelming loan spell at Chelsea last year but is keen on a return to Stamford Bridge and has been offered a six-year deal. Negotiations over the Portugal international began when Chelsea’s move for the Atlético forward Samu Omorodion collapsed last week. Atlético have needed to sell a player to finance their €42m (£36m) move for Conor Gallagher, who has a year left on his deal. Their determination to sell Félix, who was on loan at Barcelona last season, means ­Chelsea will be able to sell the ­England ­midfielder and avoid losing him on a free transfer next year. Gallagher had been in limbo but is set to complete his ­move in the next 48 hours. Maresca will need to find space in his crowded attack for Félix. The former Benfica star is a creative ­talent who operates in similar areas to Christopher Nkunku and Cole Palmer. Armando Broja, Trevoh Chalobah, Ben Chilwell, Djordje Petrovic, ­Carney Chukwuemeka and David Datro Fofana are also up for sale. Napoli are pushing to sign Romelu Lukaku, and Kepa ­Arrizabalaga is free to leave. It is unclear if Sterling will receive similar treatment to other out-of-favour players, with Chelsea barring Broja, Gallagher and Chalobah from first-team facilities while they wait for moves. Sterling does not expect to be involved when Chelsea, who are supportive of the selection call that dominated Maresca’s first game in charge, host Servette in the first leg of their Europa Conference League playoff on Thursday. The issue for Chelsea, who have embarked on another heavy summer of spending under the ownership of Clearlake Capital and Todd Boehly, will be finding a buyer for Sterling. The England international is settled in London and has already rebuffed interest from the Saudi Pro League. There has been preliminary interest from Juventus, with talk of a swap deal involving Federico Chiesa, but the finances are likely to be ­prohibitive for the Italian club. Chelsea, who are confident of complying with the Premier League’s profitability and sustainability rules (PSR), have looked to cut their wage bill and that makes Sterling vulnerable given he is one of their highest earners. But given the widespread concerns over PSR, it will not be easy to sell the forward. Sterling, signed for £47.5m two years ago, is not in a rush to leave Chelsea and has been caught off-guard by the situation. He was involved in ­pre‑season and was described recently by Maresca as an important player. Eyebrows were raised at Sterling appearing on Monday in a promotional image for Chelsea’s new sleeve sponsor. Maresca’s attacking options will increase after Chelsea ­reached an agreement with Atlético for Félix. That move would pave the way for ­Gallagher, an academy product, to join the Spanish club. Chalobah, another homegrown talent, has been told he is not in Maresca’s plans but the defender has not ruled out ­staying at his boyhood club. There have been no developments with Broja and it is understood that serious interest in Chilwell, who was vice-captain last season, is yet to materialise. Chukwuemeka, who missed much of last season with a knee problem, was not involved against City and is expected to depart. The midfielder, who could go on loan or on a permanent deal, is looking for the right opportunity and has been linked with Napoli and Barcelona. Chelsea have had a long dialogue with Napoli over Lukaku and could sign the Nigeria forward Victor ­Osimhen from the Italian club. Talks over Osimhen have centred on a loan but it remains to be seen if Chelsea are prepared to meet his wage demands. Paris Saint-Germain are said to have cooled their interest in the former Lille striker.
