Thomas Tuchel has insisted Chelsea's squad only needs a facelift for next season, ahead of taking on a Manchester United side that Ralf Rangnick reckons requires "open heart surgery". Blues coach Tuchel will go head to head with mentor Rangnick at Old Trafford in Thursday's Premier League clash, adamant that Chelsea do not need the emergency operation being talked about by the Red Devils. Where Rangnick believes new United boss Erik Ten Hag will have to breathe new life into the Old Trafford ranks, Tuchel still remains confident Chelsea's needs only run skin deep.
