I feel we are really really missing him. When he plays we normally get control of midfield and can't suffocate teams in their own half. He also protects the centre backs and allows us to play a high line as the defenders can be fairly sure that their midfielders won't have a lot of time and space to pick a pass as Fabregas did today. His presence also gives Xabi more time to play, and Gerrard more freedom to get forward. It's much harder to do that with Hamman who plays much deeper than Momo and is much much less mobile. Clearly having a forward who constituted a threat would help a bit too.
