It’s been just over a month since Manchester United gave Jose Mourinho his marching orders.

Since then, the Red Devils have enjoyed better days under interim boss Ole Gunnar Solskjaer.

With the 45-year-old at the helm, United are yet to taste defeat, winning six on the bounce in all competitions.

In the meantime, Mourinho has returned to the spotlight, most recently as a guest on beIN SPORTS in Qatar earlier this week.

And after such a departure, it’s surprising that the Portuguese has remained tight-lipped on the matter.

However, that’s because he simply isn’t allowed to spill the beans.

According to Duncan Castles via the Daily Record, the severance package in his United contract was dependent on maintaining a non-disclosure agreement.

A breach of the contract and the Manchester side wouldn’t have to pay off Mourinho, a sum that will total to £24million.

And Castles added that the former United boss was reminded of this through an email the day after he faced the chop.

That explains a lot.

Mourinho was approached by Sky Sports shortly after his sacking and he refused to talk about the club, saying: “I keep the good things and I don’t speak about anything that happened in the club.

“We could speak about so many good things and we could speak about not as good…that’s not me. It’s finished.

“Manchester United has a future without me and I have a future without Manchester United, so why should I now be sharing with you or even with the supporters any of my feelings?”

And during that appearance on Qatar TV earlier in the week, he spoke about matters such as player-manager relationships and the inclusion of those higher up such as CEOs, football directors and owners.

These are topics that arguably could have highlighted the issues United faced during Mourinho’s reign but their former boss was quick to say: “I was not speaking about my experience with Manchester United at all, I am speaking about generality.”

So, it seems anyone trying to obtain information surrounding Mourinho’s time at Old Trafford from the man himself will be facing a very tough battle.
