Arsenal striker Carlos Vela can't guarantee staying with Real Sociedad.

Real want to turn the Mexican's loan into a permanent deal at the end of the season.

But Vela said: "I'll need time to think about it. Now I cannot tell you anything. First I want to finish the season, leaving the team in a good position and providing more goals and assists.

"Then, when the market opens, I'll see if the best choice is to come here."
