His record is very good. What makes the Utd job different is that he is not joining a team like he did when he joined Chelsea, Inter, Real and Chelsea again i.e. a team at or very near the top, with a nucleus of great players in their prime. What works to his advantage however is that there is currently no stand out team in the EPL and a good foray in the transfer market could see any of 5-6 teams challenge for the league next season.
