The Chilean is adamant he is already operating on the same level as his rivals and Wenger believes his star man is capable of reaching heights similar to those of the Barcelona and Real Madrid superstars.
"He[Sanchez] is ambitious and, of course, he is a guy who wants to win every single game," Wenger insisted.
"It's good to have that kind of ambition.
"He has the potential and the quality and it's just up to him to show that.
"Ronaldo and Messi have done it for years so the consistency of their performances speaks for them. I hope Alexis can get that."
