Hakim Ziyech scored a last-minute winner as Chelsea edged past Crystal Palace on their return to Premier League action.
Thomas Tuchel’s side last played in the top flight almost a month ago when they defeated Tottenham, and have had a week’s rest since winning the Club World Cup last Saturday.
It looked like they would be frustrated by their hosts but Ziyech popped up at the back post to stroke in a delightful volley from Marcos Alonso’s cross.
Moroccan Ziyech had converted earlier in the second half when he swept home following Jack Butland’s save, but Romelu Lukaku was adjudged to be offside by VAR.
Vicente Guaita had made good saves in the first half from N’Golo Kante’s effort and Antonio Rudiger’s long range thunderbolt, before the Palace goalkeeper was taken off at half-time because of a knee injury.
The home side, meanwhile, did not have a single shot on target in the entire contest – both Michael Oliseh and Wilfried Zaha failing to work Edouard Mendy from promising positions.
