Man Utd are already through, and tonight, Liverpool will go to Stamford bridge with the intentions of upsetting the Londoners for the 3rd time in 4 years.
The previous two times have saw Liverpool dramatically take it with a penalty shoot-out last year and a dubious goals to years prior.
I think Chelsea's home advantage tonight will be the deciding factor. Barcelona playe dbrilliantly against Man Utd in the first leg at the Nou Camp but Man Utd were untouchable at home.
Liverpool's last two victories against Chelsea have been at anfield - the place they also knocked Arsenal out of the Champions League.
With all logic aside, Liverpool have always defied the odds in this competition which is why tonight's match cannot be called one way or the other.
