There's a lot less pressure in taking the job now. First season expectation is top 4 not to challenge for the title and he can shape the squad in anyway he wants as they have performed so poorly.It's better to inherit a team who's lacking in confidence and forgot how to win rather than inherit league title winners?
Plus that title winning squad needed a lot of work due to some players being on their way down (Ferdinand, Vidic, RVP)
