Chelsea defender Andreas Christensen was substituted after picking up what looked like a groin injury in Denmark’s 1-0 win over Switzerland in a Euro 2020 qualifier last night.

The centre-back was taken off with three minutes remaining during the game and there hasn’t been any indication yet about the seriousness of the problem.

Frank Lampard has had to cope with a number of defenders picking up injuries at the start of this season, and this latest setback for Christensen will cause the Blues boss more selection headaches.

Antonio Rudiger is believed to be back in training after recovering from his own groin issue but he hasn’t played since being taken off against Wolves in the 5-2 win a month ago.

Unless Christensen’s latest injury only turns out to be a minor problem, it appears that Kurt Zouma and Fikayo Tomori will continue as the centre-back partnership when Chelsea face Newcastle at Stamford Bridge on Saturday.
