Real Sociedad striker has refused to rule out a move to Arsenal and has insisted that he will think hard about his future in the summer break.
The Mexican has been in brilliant form this season for the La Liga club, scoring 16 goals this season in 37 appearances.
His form has attracted interest from a lot of clubs across Europe, including the Gunners, who have a buy-back clause of £3.3m in his contract. The north London club are looking to exercise that option this season and bring him back to the Emirates, with Arsenal in desperate need of a striker to provide backup for Olivier Giroud.
Sociedad are willing to pay £4.9m to buy out Vela's clause but the Gunners want twice that amount to allow the 25-year-old to stay in Spain. Arsenal are also interested in winger Antoine Griezmann and his transfer may also play a notable role in deciding Vela's future.
Vela revealed that the club are working on his clause so that he can stay with them next season but he is still not sure if he wants to continue in Spain or move to the Emirates to give himself one last chance to prove himself in the Premier League.
"The club [Sociedad] is working so that I stay here. I am working on it in my own way too. But there is still not anything concrete, it is not anything that is ready to be closed. There is still time for it to be done," Vela told AS.
"I wanted to finish the season well, in the best form, I wanted to have some days to think about what to do, where would be my best option, what is the best for my future, and then decide.
"As of today I have not decided anything, nor have I said anything. These days I will rest to mentally rest and analyse what is the best thing to do," he added.
