The highly-rated midfielder is out of contract at the end of the season and has been strongly linked with a move to Manchester United.
Emery has called on Ramsey to keep his mind focused on playing well, rather than his future.
“I spoke with him last week,” Emery said. “I said: I want you focused only on training and only on the match, you show us the capacity to help the team.
“The contract is another thing for his agent and the club but we want and I need his focus only on training, only on the match and on his performance each day.”
