The 36-year-old has dropped to second-choice goalkeeper behind summer arrival Bernd Leno this season and has only featured 11 times in all competitions so far for the Gunners.
Cech has kept more clean sheets than any other in Premier League history but with his contract expiring this summer, Emery admits he is unsure if the Czech Republic shot-stopper will extend his Emirates stay.
When asked about Cech’s long-term future, Emery replied:
“I don’t know now.
“This is a question for the club and the player to deal with our necessary things with the goalkeeper.
“All situations like this, we will speak with the player and with the club but at the moment, I want his focus the same, each training, each match.
“He is going to play Saturday to give us his performance and then we are going to decide also within what is the best for him and for the club.”
Although his future remains in doubt, it’s highly unlikely that Arsenal will offload Cech this month as they need a back-up option for Leno should the German be unavailable for any reason.
