Torres plus another bloke up front could and should work. Problem right now is Keane isn't carrying his own weight, both Kuyt and Babel has looked much better when playing there so far this season. Both of them could do a good job alongside Torres. However I've seen Keane playing brilliantly before, if he could just get up to his normal standards I think a Torres-Keane partnership should work. Having said that the 4231 formation from last season seemed to work very well, wouldn't mind seeing it again. If Rafa is desperate to keep Robbie in the side then I don't see a reason why he couldn't operate in the Babel/Kuyt position from last season.
