"It is a completely different system here to what we are used to," Henry said. " If a player has a contract in the United States they fulfil the contract.  Over here, it seems players have much more say-so about where they are.  Frankly, where we are, we don't want a player at the club who doesn't want to be at the club.  It's really up to us to provide the kind of leadership, on and off the field, that any player at the club or who is coming to the club wants to be here."
