Chelsea beat London rivals Tottenham Hotspur 1-0 on Thursday thanks to a goal by Argentina's Enzo Fernández which restored the Blues to fourth place in the Premier League, boosting their hopes of a return to the Champions League next season.
Fernández was left unmarked to head home in the 50th minute from a perfect cross by Cole Palmer on the England forward's return from a brief injury absence, in front of England coach Thomas Tuchel who was at Stamford Bridge.
Chelsea thought they had a second goal soon after but Moisés Caicedo's volley was ruled out after a VAR check for offside.
