Arsenal will hand late fitness tests to Laurent Koscielny and Granit Xhaka ahead of Sunday's fixture at Everton .
Koscielny and Xhaka have been struggling with respective foot and groin injuries but Aaron Ramsey is fit after a minor groin problem of his own.
Lucas Torreira remains suspended, Danny Welbeck is out with an ankle injury, and knee issues continue to sideline Hector Bellerin and Rob Holding.
Emery said: "Aaron trained normally and all the players are working.
"We are thinking game by game and we know seven matches, and five away, for us is a big challenge. We have confidence now but we know it is very difficult. It's a long way for the last matches.

"We hope we can take the next matches. Three points like Sunday with Everton is the most important because we know also the other teams are going to demand a lot of us.
"Everton won against Chelsea 2-0 and drew against Liverpool in their last matches at home."
Mesut Ozil, 30, is pushing to retain his place, having featured less for Emery in away fixtures.
"(Mesut) is working well and helping us. I am very happy with him," added Emery.
