Speaking to Boylesport, Michael Owen said: "Timo Werner had a good record and he scored a lot of goals before he came to the Premier League. We're quite good at tarnishing someone with one brush.
"But with all due respect, I think that Arsenal need to look at some of the best strikers in the world if they're serious about truly competing for the Premier League and Champions League.
"You need one the best three, maybe four strikers in the world to dominate and win those games, and I wouldn't put Timo in that category."
Werner has been linked with a return to the Premier League with both Arsenal and Manchester United said to be interested in the 27-year-old.
The German forward has fallen out of favour at RB Leipzig and could be on the move once the winter transfer window reopens on January 1.
