RE-Cisse and Pack: as others have said, you only notice this sort of player when they aren't there.
Remember when Makelele left Real for Chelski, same time as Beckham came in, Zidane said "We've bought a new coat of gold paint for the Bentley, but sold the engine"
Cisse in particular never did anything spectacular, but was a real 100% player. Physical, not especially gifted, but worked like a Trojan, doing all the unglamorous stuff. Pack could play a bit more, but also was a very disciplined player who read the game well.
