If there is one story that sums up Mourinho's time at United, it comes from the club's pre-season tour of the United States in 2018.

The trip's commercial opportunities included a “training session” at the impressive UCLA campus in Los Angeles with then-Late, Late Show host James Corden.

The event featured a host of local children coached by Corden who played against the United trio of Juan Mata, Chris Smalling and Ander Herrera, led by Mourinho.

Filming was scheduled for early morning before the scheduled team training.

Despite an early start after a day off after Mourinho added the event to the tour schedule at short notice, the players expressed their willingness to fulfill the commitment.

But at the time of his departure, Mourinho was nowhere to be seen. The tour group was told that he had gone ahead. Upon arrival, security announced that Mourinho was in the dressing room and was not in a good mood.

Although some of those involved were on site in the early hours of the morning, Mourinho's involvement, it was stressed, was certainly at stake.

If you look at the footage of the event now, you can't see any of it. Mourinho was committed, had fun and, above all, ensured that the young people had an unforgettable memory, external for the rest of her life.

When speaking to numerous sources about Mourinho's time at Old Trafford, the contradiction between somber moods and charm, sometimes changing in a matter of seconds, is repeated by all.
