Just a silly thing to say. Eto'o isn't too far off being a goal a game this season. That's not a case of "well he's had more chances". That's a top class striker doing things no other striker in the game is doing right now
Some players can't handle playing for the biggest clubs, with the pressure of expectation every single game. When Kevin Phillips was scoring 30 in a season for Sunderland, was that proof he'd score 50 for United?! Of course not. It just doesn't work like that
Yeah but Sunderland and Phillips are a totally different level to Liverpool and Torres. Nobody ever thought Phillips could score a similar amount of goals for United. The gulf in quality between the two teams/players in this situation isn't as large as the comparison you have drawn.
I admit this is a totally hypothetical situation and that no arguement can convince everybody. But my opinion is that Villa and Torres would be more clinical in that Barcelona team than Eto'o, based on the fact that I've seen Eto'o miss so many chances this season, and it seems like when Torres gets a chance similar to Eto'o, he buries it. Maybe thats something to do with the supposed difference in ability between the opposition, I'm not sure, but it seems like Torres is more clinical.
