Chelsea are prepared to sell Marc Cucurella this summer providing their valuation is met, talkSPORT understands.The 27-year-old left-back has three years left on his contract, having penned fresh terms last year, and is understood to be open to a move away from Stamford Bridge this summer.Cucurella is set to play a leading role for Spain at the 2026 World CupGettyAtletico Madrid view Cucurella as a leading target and are set to open talks with Chelsea in the coming weeks.Adding a new left-back is a top priority despite only signing Matteo Ruggeri last year, and talks on the player’s side are already underway.Atleti could move quickly in the hope of striking a deal with Chelsea before other clubs have decided whether to enter the race.Barcelona are another potential suitor, but nothing is advancing yet. Barcelona would likely need a defender to leave first.Real Madrid have also been linked, but sources downplay a move as it stands. Real’s priority in defence is to sign a centre-back, and negotiations have resumed with Ibrahima Konate now he is a free agent, despite Real ruling themselves out last year. An agreement could be formalised following the presidential elections.Manchester City tried to sign Cucurella when at Brighton, prior to his move to Chelsea in August 2022 and links will be natural now that former Blues boss Enzo Maresca is set to replace Pep Guardiola. Cucurella retains some admirers within the club.Yet City view Nico O’Reilly as their starting left back, and are currently prioritising a right-back. Newcastle’s Tino Livramento is one name appreciated. The club’s position would only change if Josko Gvardiol is sold. Bayern are currently considering whether to make a move for the Croatian defender this summer.Cucurella joined Chelsea from Brighton for an initial £55m, with the fee rising to £62m with add-ons. He has gone on to make 162 appearances, scoring nine goals and despite a difficult start, has become a fan favourite and one of Chelsea’s most consistent performers.Cucurella joined Chelsea in a deal worth up to £62m in 2022GettyYet following Chelsea’s 5-2 Champions League loss to PSG at the Parc des Princes, Cucurella questioned the club’s youth led model.“We lacked experience,” Cucurella told The Athletic. “For a lot of players, it was the first time playing a match of that calibre, and we paid the price…“Results like that are always hard to take. You are fighting and training every day only to realise, at the very end, that when games matter, we are still a bit away from the top level.“I understand this is part of the club’s policy, and that they want to take this direction – signing young players and looking to the future. But, for all of us who are still here and want to win big things, moments like this make you feel discouraged.“We have a good core of players. The foundations are there. But to fight for major trophies such as the Premier League or the Champions League, you need more. Signing young players only might complicate achieving those goals. Against PSG, we lacked players that had gone through situations like that.“You need time as well, and I know the young players are the ones that will have the experience in the future. But you need to find the balance between both worlds.”Chelsea will insist their valuation for Marc Cucurella is metCucurella price tagChelsea remain calm about Cucurella’s future, with club insiders pointing to the fact he has three years left on his contract and so his value is well protected.Yet talkSPORT understands a sale is not discounted this summer.
