Torres was in tears at the final whistle of the first-leg of their Europa League playoff given the raft of chances he failed to convert.
Suarez said, "He has done nothing wrong, he doesn't have to cry.
"A footballer does not have to cry, he has to improve. He hasn't done anything wrong.
"If what Ferran failed at was what (Ousmane) Dembele failed at, they (the fans) would kill him.
"Ferran always approaches the ball poorly, he doesn't even look at it."
