Ronaldo has been terrific but take a look what he has around him, Nani, Rooney, Tevez, Giggs, and Scholes. If you took Ronaldo away from United it would not be as bad as it would be if you took Torres from Liverpool.
Look at the support that Torres has up front, players like Dirk Kuyt and Voronin. Not exactly Nani and Rooney is it. So for those reason I can not help but think that Torres should be near the top of the EPL Player of the year race.
