Torres is more talented footballer and he's got that quality to create his own goals, which is a rare thing for a target man. He's younger too so that makes him more attractive option. I'd understand why teams would choose Torres over Drogba.
But i'm different. I admire these strikers like Drogba and Amauri who literally rape defenses, who are a pain in the ass all match long, who fight, foul, tackle, pop up out of nowhere. And you can't deny Drogba's talent either.
For me Drogba will always be > Torres.
