"I hope to join them [Arsenal] as soon as possible," Vela told Spanish newspaper Libero. "I will keep on working hard to improve to fit in quickly."
Vela is also keeping a keen eye on the progress of Arsene Wenger's side.
"I'll definitely be following them and hope they stay on top in the Premier League," he said.
"I'm also happy that Arsenal made it through to the next stage of the Champions League. It would be nice if they get a rival from the Spanish League. Let's wait and see."
