Chelsea want to keep striker Christopher Nkunku despite growing interest from abroad.
Nkunku is under contract at Stamford Bridge until June 2029, having signed a six-year contract upon his arrival from RB Leipzig in the summer of 2023.
Chelsea paid Leipzig £52 million for Nkunku, who has so far scored 15 goals in 41 appearances for the Blues, mainly as a substitute.
Reports in Spain recently claimed that Barcelona was on Nkunku's long list of foreign admirers.
Closer to home, Manchester United have also been linked with a possible transfer for the 27-year-old.
Chelsea manager Maresca was asked by journalists earlier this season if Nkunku was unhappy with his lack of playing time.
Christopher Nkunku is wanted by several foreign clubs, but Chelsea are willing to retain him
Nkunku has scored 15 goals in 41 games for the Blues, including a hat-trick against Barrow.
Manager Enzo Maresca said earlier this season that Nkunku was “absolutely not” for sale.
Maresca replied: 'Not at all. I spoke to Christo a few days ago and he didn't say he wasn't happy.'
After declaring that Nkunku 'is not at all' for sale, Maresca added: 'The problem with Christo, not the problem, but the same issue that we have mentioned many times; If you play with Cole (Palmer), Joao (Felix), Christo, Jadon (Sancho) or Noni (Madueke), who defends? His ability is not to defend. We tried the last game with Joao and Cole together.
“Probably Christo's best moment with us was in the preseason, playing in his position. Since we started, he plays as a nine for us. Against City he played as a winger; knowing that this is not your best position. His best position is 10 but Cole plays there. We need balance.'
