Saliba arrived with the rest of the squad in west London with Mikel Arteta hopeful it isn’t a serious injury.

‘Yesterday in training he was uncomfortable, so we need to explore a little bit more what happened,’ Arteta said ahead of kick-off.

‘I don’t think it’s something major, but enough not to be involved in the game.’

Mikel Arteta has selected two of his summer signings in their place with Piero Hincapie and Cristhian Mosquera starting for the first time together at centre-half at Stamford Bridge.

Viktor Gyokeres is back in the Arsenal squad having missed the last four games.

The Sweden international was forced off at half-time against Burnley at the start of the month with a hamstring injury but is back among the subs today.

Martin Odegaard returned off the bench midweek against Bayern Munich with the captain again named among the substitutes today with Eberechi Eze starting ahead of him.

Gabriel Martinelli, another to return from injury during the week, replaces Leandro Trossard who is left out of the squad.

Trossard picked up a knock in the first-half against Bayern with Martinelli in to replace him on the left.
