Fergie won the league in his last season. Admittedly the team was on the decline but he still left a very good team. Following him was always going to be impossible though.
Evra, Vidic, Ferdinand, Carrick and Berbatov were all in decline whilst Scholes and Giggs had been coaxed out of retirement homes for one last hurrah.
That team won the league on fumes and sheer willpower.
