I thgink it is more to do with Kalou's hunger to make an impression that makes the significant difference in his performance. When he used to come on as a sub in previous seasons, he came on to impress which usually either came with a goal or a bright spark of inspiration/energy with his hard work ethic made a difference. Anyway, didn't see much, but the way Romeu was really was superb, nice to see another good youngster on the cards. Sadden that Josh couldn't be apart of the journey or match in some way. How did Kevin play?
