New signing Henrikh Mkhitaryan will have to wait to make his Arsenal debut with the winger cup-tied for Wednesday’s Carabao Cup semi-final second leg against Chelsea.
The former Manchester United player appeared in the quarter-finals for his former club, but Aaron Ramsey (illness) and Nacho Monreal (leg) could feature.
Cesc Fabregas (hamstring) and Alvaro Morata (back) are out for Chelsea.
However, Andreas Christensen (head) is available for selection.
The defender was taken off in the 4-0 win at Brighton at the weekend but Chelsea boss Antonio Conte confirmed he has returned to training.
Wednesday’s tie is finely poised after the two sides drew 0-0 at Stamford Bridge a fortnight ago.
Who Will Win Tonight?
