Arsenal head to Tottenham, where they will come up against in-form Welshman Bale, who has drawn comparisons with Europe's best after his match-winning performances this season.
Wenger believes his own talented midfielder has everything ahead of him.
"Bale is the flavour of the moment. When you look at Wilshere, who will deny that this guy will get 100 caps for England? Nobody, if he has no injury," said Wenger.
"My worry is not to compare Wilshere with anyone else. My only worry when you are a footballer player of that talent is to become as good as you can become.
"That is the only thing that is of interest to me. I leave the comparisons to other people. My job is to get the best out of him."
