Arsenal captain Laurent Koscielny is expected to be fit for Sunday's Premier League visit of Brighton .
The defender came off in the 3-1 Europa League semi-final first leg win over Valencia on Thursday but is in contention to face the Seagulls.
Nacho Monreal replaced Koscielny and could come in from the start having overcome his own calf problem, while Danny Welbeck (ankle), Hector Bellerin and Rob Holding (both knee) are all out for the season.
Having lost four of their last five Premier League games, Arsenal sit two points behind Chelsea - who are also in contention for a place in the Europa League final - with two games remaining.
Away defeats to Everton , Wolves and Leicester and a rare home loss to Crystal Palace saw Emery's side come in for heavy criticism.

They shipped 10 goals in those games, with Emery recently coming out to give his backing to under-fire defender Shkodran Mustafi.
Sokratis admits some of the criticism aimed at the squad has been justified but that anyone in the ranks can make mistakes and none of the players are affected psychologically by it.
"Of course, when you play at a team like Arsenal and you lose three games of course you hear critics and you have to improve," he added.
"We are here to improve, to give the best for the club, for the fans and for us also.

"I think that the biggest point is that we have to stay focused. We are a big family and we are all together, we stay all together. In one week, for example, (Laurent) Koscielny makes a mistake or I make a mistake or Mustafi the same, Nacho (Monreal) too.
"We are people and not robots. Of course we have to improve and we have every game to give 100 per cent and I think the critics are good to hear, to improve, but they do not touch us mentally."
Provisional squad: Leno, Cech, Maitland-Niles, Lichtsteiner, Jenkinson, Mustafi, Koscielny, Mavropanos, Papastathopoulos, Monreal, Kolasinac, Xhaka, Guendouzi, Torreira, Elneny, Iwobi, Mkhitaryan, Ozil, Aubameyang, Lacazette, Nketiah.
