We bought him from a team where he was playing regularly, so the excuse of not being fit is not tenable. This is another example of a manager too afraid to change what he thinks is a winning formula. We are(were) top of the league so play the same team till the wheels fall off. Its been a wenger tactic for years now. However it means that when players are now called in under an emergency, then THEY are neither fit or in sync with the rest of the team. Good managers rotate routinely to keep the team fresh and everyone on their toes.
