'They are very competitive, have very good players and we need every single player, and our mentality together to be stronger than in the last match'.
Arsenal's 5-1 win over Fulham in their last game before the global break was the ninth consecutive victory under Emery, and was played to the soundtrack of Arsenal fans singing: "We've got our Arsenal back".
But Emery warned the increasingly optimistic fanbase against getting carried away.
The midfielder, who played in Switzerland's 2-1 defeat to Belgium on Saturday, is in no doubt that Emery is to thank for his revival, telling the Daily Mail: "On a tactical level, the manager has really helped me". Emery now expects a tough test to extend the run when Leicester visit the Emirates Stadium on Monday night. "It is going well and I am improving, but we can still improve". For me now, the most important thing is not to rush'.

Arsene Wenger reckons there is still a chance that Arsenal midfielder Aaron Ramsey will remain a Gunners player beyond the end of this season.
Ramsey will be free to sign a pre-contract agreement with foreign clubs next January unless Arsenal made a decision to cut their losses and sell the Welshman in a cut-price deal in the transfer window.
Ramsey said during the global break that he has no intention of pushing for a move in January, and Emery urged the midfielder to stay focused on the next match. I think we have to continue doing a lot of the things to get better.
