Samir Nasri has cast more doubt over his Arsenal future by admitting he may not sign a new contract.
The 23-year-old midfielder, who is entering the final year of his current deal, has also refused to rule out a move to Manchester United.
Speaking to French sports programme Telefoot, Nasri said: "I don't know if I will sign a new contract, the discussions are ongoing.
"Do I want to go to United? First, we should see if it's real and concrete."
Manchester United defender Patrice Evra invited his French team-mate Nasri to move to Old Trafford last month.
The versatile attacker, who joined the Gunners in 2008 from Marseille, has scored 27 goals in 124 appearances.
He particularly impressed during the first half of last season, which was his most productive to date at the Emirates, scoring 15 goals in 45 games in total during the campaign.
