Last night, Barcelona beat Liverpool 3-0 in the first leg of the Champions League semi-final.
Personally, I felt that Liverpool played well and was better than Barcelona during long stretches. The players were good but could not score the 2-3 clear chances they had. Salah, ManÃ©, Wijnaldum and Milner all came really close. The Barcelona players did though, with one goal by Luis Suarez and two by Lionel Messi (his free-kick at the 80th minute was amazing).
The probability of Liverpool winning the return tie by 4-0 (or 5-1, etc.) is very low (a few percents at most). Liverpool will have to score very early and completely dominate the midfield.
Can this happen? I have some doubts, to be honest, but history shows that, at Anfield, anything can happen.
