BR - If you are looking for a day when the Chelsea season would be fully accounted for, it would be the opening leg of the Champions League semifinal against Barcelona. It's a match the Blues simply must win.
Let's get one thing out of the way straight out—Chelsea will not win at Camp Nou. The Catalans are far too fierce a side, and far too comfortable in the warm embrace of their home to let a mammoth upset like that happen.
Barca can't afford to underestimate Chelsea, at Camp Nou or away. Gonna be two awesome matches.
