Think Chelsea are going to bunker in, pack 11 men behind the ball and try and hold out for a 1-0 win against Barcelona? Think again. Yes, a 1-0 home result that denies Barcelona an away goal is a good result for the Blues, but they know that they'll be hard pressed to get a draw or an away goal at the Camp Nou. They need to try to score again, so they're not making defensive subs. Solomon Kalou, who has been given a new lease of life in the side under Roberto Di Matteo, has come on for Juan Mata.
It's an attacking player for attacking player move, so not inherently positive, but Mata has struggled to make an impact on the game. He's a spectacular player for Chelsea when they have the ball more than their opponents, but that hasn't been the case in this match. In this situation, a lot of managers would bring on a player like Michael Essien to try and hold onto a clean sheet, but RDM has opted for a speedy forward instead.
