Real Sociedad striker Carlos Vela is looking forward to facing Champions League opponents Manchester United tomorrow.
The Mexican will be reunited with former Arsenal teammate Robin van Persie at Old Trafford.
"I learned a lot from him," Vela told The Independent. "For me, he's the best striker in the world and it was a pleasure to be able to share moments in training with him.
"We used to sit next to each other in the dressing room and talk. I used to ask him about his movement, what was going through his mind when he did certain things, and he would explain. If I was missing something in my game he'd speak to me and give me advice and I'm grateful for that."
