Well, when you have a quality player in your midfield you can do things like that... If Liverpool want to have any chance whatsoever of overturning 3-1 deficit they need to make radical changes in formation and personel. Second leg, has to be 4-4-2. I'd put Gerrard on right flank (injury permitting) to pre-occupy Essien, then give Mascherano licence to play box to box through central midfield. I'd have Babel supporting Torres upfront, and Agger at centre half to dictate initial play.
