Carlos Vela admits that Arsenal do have the option to re-sign him from Real Sociedad and says he could return one day.
The Mexican international left the Gunners for Real Sociedad on loan in 2011 before sealing a permanent transfer in 2012.
Last season saw Vela go on a terrific run of form that saw him score 14 goals in La Liga despite playing predominantly on the right wing.
Such form has seen him linked with a return to the Emirates stadium with rumours of a buy-back option for Arsenal being in place.
Vela, speaking to Sky Sports before the game against Manchester United, confirmed that there was a release clause but says now is not the right time to return to play under Arsene Wenger.
When pushed, however, he did admit that he hasn't closed the door to a return.
"Every summer they can take the buy option. But for the moment it is difficult.
"They are good now, I am good now. I don't think it is the best moment to go back to Arsenal."
When asked whether he could make a return at some point during the future he said: "Maybe."
