I think you'll find Tevez' stats are exceptional alongside Ronaldo and Rooney as it is.
Babel has potential, but the odd thing I see with him is that he only ever seems to be dangerous for around 5 minutes a game. His decision making will improve (it has to improve) because at the moment it's woeful at times, there's potential there though.
Benayoun isn't as quick, but his decision making is a lot better, I'd go for him there. The fact he's bagged 2 hat-tricks this season is pretty impressive too, and he'll do the nitty-gritty if he has to.
We haven't seen the best of Babel yet, but he has masses of potential. Could become anything.
Agree with you with respect to his decision making. Also seems to look better off the bench when teams are tired.
Think he will make that second striker position his own in the next few years, can't see him staying on the flanks.
Yossi is a great player, fantastic technique but he doesn't provide an end product enough. Probably as effective as we've got though.
