Indeed, the Czech international has made 48 saves already in Europe this term (another competition-high), a remarkable 39 more than Barcelona number one Victor Valdes.

On the one occasion Cech was beaten in the first-leg, defender Ashley Cole was on hand to save his goalkeeper, in doing so taking the Blues’ tally of goal-line clearances in Europe to four, the most of all teams.

Stopping the likes of Messi and Xavi is going to be extremely tough for Roberto Di Matteo’s side next week, but the Blues have proven they have the fight and ability to dig deep and defend for their lives.
