Stephan Lichtsteiner says he will only sign a new deal at Arsenal if he is guaranteed regular first-team football next season.
The 35-year-old joined on a free transfer from Juventus last summer and has made 21 appearances.
He revealed talks have begun over a fresh agreement but his primary concern is making Switzerland’s squad should they reach Euro 2020.
“This will need time,” he said. “The fact that I play at a top club at the age of 35 says enough. There have been talks [with Arsenal]. We have to see if it suits both sides.
“Arsenal is a big club, I feel very happy. But I want to play regularly with regard to Euro 2020.
"It was okay this year. But if the coach says that he no longer counts on me, I have to worry."
Switzerland begin their campaign against Georgia on Saturday and are in Group C along with Denmark, Republic of Ireland and Gibraltar.
