Yaaas Broncos!
Was that really the case though?

He was pictured entering Carrington with Ferguson and for some reason Albert Morgan shortly after it was made official he was taking over in May.
No doubt his contract with Everton ran until the end of June, but then wasn't Mourinho still under contract at Real when he started work early at Chelsea in 2013?

He 'took the helm' on 1 July, that being the day after his Everton deal lapsed.
There will be plenty of cases where a manager starts work before a contract officially comes to an end, but those cases will have been negotiated individually and possibly had compensation agreements. In this case Chelsea have no interest in letting him out of it early and his severance pay would have been on the basis of seeing out the 'contract year'.
