The Gunners have bounced back since losing their first two fixtures to Manchester City and Chelsea, to record 10 straight victories in all competitions.
The latest came on Monday night, as they fought back to defeat Leicester City 3-1 and move into fourth place, two points behind leaders City.
“We need to be calm. For us it’s very important to beat Leicester because they are behind us but near [in the table] .
“We are also looking at the teams in front us like Liverpool, Manchester City and Chelsea.
“We were controlling the match and finding the chances to score. The first 30 minutes was a difficult moment,” Emery told a news conference after the game at the Emirates.
