Mourinho is sure to have plenty to say about the game featuring another of his former clubs, as well as a team he has not held in the highest esteem during his time in English football.
The Portuguese specialist now has right to head another club.
The pay-out leaves the 55-year-old Portuguese free to take up the permanent job in Madrid, despite the disappointing end to his two-and-a-half year spell at Old Trafford, when Santiago Solari's time as the European champion's interim boss ends. His team won the Football League Super Cup, EFL Cup and Europa League.
Earlier, YEN.com.gh reported that Jose Mourinho is reportedly ready to pick up another job barely one month after being sacked by Manchester United.
Thankfully for him, he can go wherever he wants, because it has emerged that he officially received his pay-off from Manchester United in the form of a £15 million compensation package, immediately upon his sacking.
"When any professional returns to a club it is a tremendous honour".
Mourinho and Tottenham manager Mauricio Pochettino are the front-runners for the job when Real do make a decision on Lopetegui's long-term successor, but the latter is not available at the moment and is likely to cost more than £40m to get out of his contract in north London.
But the manager was let go by the club due to their struggles in all competitions this campaign as they were sixth on the log before he was sacked. But, they have initiated talks with his representatives ahead of what could be a possible move in the summer, depending on Solari's performance for the rest of the season.
Mourinho could be "invited" back to the Bernabeu because of his good relationship with president Florentino Perez but also because things haven't gone according to plan for Los Blancos this season.
