IMO Chelsea looked better in the middle in the first leg. Two weak points for Chelsea atm are Fereira and Kalou, if he's to give way to Anelka or Shevchenko I can't see Liverpool going through - a bit more pressure from hosts on the flanks will make 'Pool really struggling. I simply don't rate Arbeloa and Aurelio very high, Skrtel and Carragher will be too busy to compensate, so will be players from the middle.
No matter how Liverpool start this game they have to score and this makes hosts' task a bit easier. They have too much quality in attack compared to Liverpool who rely on Torres. Unless Babel makes his top game vs shaky Fereira...
My choice will be 2-3 goals, after all it is a Semi and no matter how tempting the HW looks, it covers 1-1 as well. Morale was mentioned above, but I don't think that's a strong point, as Liverpool showed a lot of it in the past 3 years in the CL. Rating Chelsea higher atm is only based on individuals, on the other hand Benitez is certainly higher than Grant atm.
2-3 goals is good to me as it gives a good chance to cover the bet on the in-play, and I do see goals here as Liverpool need to score...
Good luck
