Mesut Ozil was a surprise starter against Burnley on Saturday, despite the German international becoming an increasingly peripheral figure in north London. He impressed against the Clarets and could retain his place for the clash on the south coast.
Lucas Torreira might also start but is just one yellow card away from picking up an automatic one-match suspension. Henrikh Mkhitaryan has been ruled out for up to six weeks with a broken foot.
Nacho Monreal and Shkodran Mustafi are both doubts because of hamstring injuries.
Hector Bellerin, Danny Welbeck, Rob Holding, Konstantinos Mavropanos and Emile Smith Rowe are long-term casualties.
Despite the prospect of facing Liverpool on December 29, Emery says he won’t hesitate to play Torreira against the Seagulls.
Asked if the Uruguay international could miss out, the Spaniard replied: “No, in my country I never did this decision.
“We are going to play the next match in Brighton and we are going to play at full-strength, not considering other options or playing with precautions.
“No, no, because it is the same three points that is in Brighton and in Liverpool.
“We are going to play first in Brighton and it is a tough match.
“It is difficult and we need every player 100 per cent focused to do all they can on the pitch for the win.
“I don’t want him to think of the possibility of sanctions for one more yellow card.
“I don’t want him to think about that.”
