Thomas Tuchel has insisted that the Chelsea team only needs one facelift for next season, before taking on a United team that Ralph Rangnick considers to need “open heart surgery”. Tuhel will face mentor Rangnik at Old Trafford, adamant that Chelsea do not need the emergency surgery that the Red Devils are talking about. Where Rangnik believes new United manager Eric Ten Hague should breathe new life into Old Trafford, Tuhel is still convinced that Chelsea’s needs are not too deep. Chelsea have lost ground to their rivals in terms of recruitment and retention for the next term due to club restrictions due to sanctions by the British government of owner Roman Abramovich. Talisman defender Antonio Rudiger will leave for Real Madrid on a free transfer this summer, with compatriot center-back Andreas Christensen also going to Barcelona. Asked what Chelsea needed this summer in the light of comments about Rangnik’s heart surgery, Tuhel replied: “Cosmetic surgery. I would be less worried if we still had the same property, if we could rely on our structure. “As this is also being questioned, we are not worried, but we know the risk that the situation may be a little more complicated. “And it can be quite complicated if you lose a player like Tony, and maybe you lose another player like Andreas with quality, both free agents. “It is quite demanding nowadays in football to lose this kind of quality, in three backs to lose two key players for free. “It can be quite demanding even if everything else stays in place. So with this theme it can be a very, very demanding summer. “I do not know if surgery is the right term for it, but I just want to be positive about it and stick to the things we can influence.” Chelsea hope to have Reese James and Antonio Rudiger back with injuries.
