Chelsea are making transfer plans behind-the-scenes despite a hectic summer window, and a rumour has now emerged involving Real Madrid.

Chelsea edge past Benfica after José Mourinho's return to Stamford Bridge

Enzo Maresca’s side grabbed a much-needed 1-0 win over José Mourinho’s Benfica earlier this week after a difficult last month.

An 18th-minute own goal from Richard Ríos proved decisive as the Blues bounced back from their opening Champions League game defeat to Bayern Munich, not to mention their dismal loss against Brighton last weekend, with all three points against the ‘special one’ and a clean sheet.

The evening carried significant sentiment as Mourinho made his first return to Stamford Bridge since November 2020.

The Portuguese tactician, who won three Premier League titles over his two spells with Chelsea, received warm chants from the home support before Maresca’s young side eventually saw out the contest.

Chelsea fielded their most youthful starting eleven in Champions League history with an average age of just 24, but they did just about enough to overcome the Primeira Liga side ahead of another vital game this weekend.

Their win provides crucial momentum ahead of this weekend’s challenging Premier League clash with Liverpool on Saturday evening, and it comes in the aftermath of reports suggesting tension between Maresca and Chelsea’s board.

Maresca isn’t entirely happy with the squad at his disposal right now (Simon Phillips), coming amid their serious centre-back shortage, with Tosin Adarabioyo, Wesley Fofana, Levi Colwill and Trevoh Chalobah all set to miss their face-off against Arne Slot’s side.

Chelsea’s boss publicly stated that he wanted a new centre-back in the summer window.

However, despite internally discussing options after Colwill’s ACL injury, and holding talks with Dean Huijsen’s camp, BlueCo couldn’t get one through the door (Simon Phillips).

It has left them desperately short, and reports suggest that Chelsea are now prioritising the signing of a new defender in January as they respond to Maresca’s central defensive crisis.

Amid Maresca and the hierarchy’s rumoured differences, one decision that threatens to escalate the Italian’s dissatisfaction would be star midfielder Enzo Fernández’s sale to Real Madrid.

Chelsea prepared to let Enzo Fernández leave in Real Madrid swap deal for Fede Valverde

Indeed, Chelsea are now reportedly willing to facilitate a swap deal that would see Fernández move to Real in exchange for Federico Valverde, according to Spanish outlet Defensa Central.

The Argentine, who’s become a figurehead of Chelsea’s midfield after an initially difficult start to life, has been called one of the club’s only two “world-class” players alongside Cole Palmer by former defender David Luiz.

Xabi Alonso’s side have been monitoring Fernández ever since his Benfica days, with the player himself apparently “delighted” by the prospect of a move to the Spanish capital.

However, while Chelsea would entertain a proposed swap which would see Valverde head in the opposite direction, Real have no plans to consider letting their star midfielder leave despite a bad start to 2025/2026.

Valverde was forced to release a statement after widespread criticism from the media, with the 27-year-old also having a nightmare during Real’s 5-2 derby defeat to Atlético Madrid last weekend.

Real’s vice-captain started in nearly every one of his 65 appearances in all competitions last season, and has been favoured by their new manager as well.

Alonso handed Valverde the armband in all of their Club World Cup games, with the 71-cap Uruguay international also playing in all but one match this season — their 5-0 win over Kairat Almaty in the Champions League.

Given Alonso’s faith in Valverde, not to mention his clear statement, it doesn’t look like the versatile ace has plans to leave any time soon.
