Ramsey is out of contract at the end of the season and talks over a new deal have reportedly broken down .
The Wales international, 27, arrived at Arsenal in 2008 and has made more than 300 appearances for the club.
Despite Ramsey's contractual situation, Emery believes the midfielder – who has featured in all six of Arsenal's league games this season – will stay focused.
"I don't think the situation will affect his performances," he told reporters ahead of Arsenal's meeting with Watford on Saturday.
"I just want to give him and the players the most stability so that they can be focused only on the games. I spoke about this situation in the pre-season and now it is the same.
"I have known and I'm going to know this same situation again because the football career for a player is very short.
"They are professionals for 10, 12 or 15 years but not more and they need to take the best performance and also work very hard in these years for their future and their family's future."
The Arsenal boss has remained tight-lipped on the midfielder's situation with the club, with Emery offering up a convoluted response when pressed on Ramsey's situation and if he wanted to keep the Wales star around .
Emery's men are on a great run of form at the moment after a difficult opening two weeks of the season, having won their last six games in all competitions and making the Gunners look like real contenders for a top-four finish once again.
Should Ramsey fail to land a new deal and exit the club next summer there would be no shortage of potential suitors, despite the fact that his time at Arsenal has been seen largely as never living up to its potential.
The Gunners, however, sit sixth in the Premier League, just six points back of league leaders Liverpool and one point back of Saturday's opponent Watford.
