Jose Mourinho was the last man to win a title at Manchester United.
The Portuguese manager won the Europa League, Carabao Cup and Community Shield in his two-and-a-half-year spell with the Red Devils.
Since his departure, Mourinho has often criticised the club for their downfall after the Ferguson era.
His current team Roma will take on Feyenoord in the UEFA Conference League final on 25th May.
Mourinho said: ‘I believe that the problem with Carlo Ancelotti was that when you coach Everton you are not about to win the Champions League.
‘And with me, you know, people they saw me taking up jobs where they thought that I could win trophies but they were not jobs where we were expected to lift trophies.
‘But when you have such a winning career on a cyclical basis so to speak, you can expect that, people can say that. Personally I’m not worried about this [being replaced by younger coaches]. I do not think and focus on the generations, I focus on quality.’
