United made it into the next round of the Champions League against all the odds when they knocked out Paris St-Germain.
Presnel Kimpembe and Kylian Mbappe struck in the first leg to make it 2-0 at Old Trafford.
And the return leg was supposed to be a stroll in the Parc des Princes but it was anything but for the French champions.
Thomas Tuchel’s men were in for a shock after the Red Devils turned the match around to run out 3-1 winners.
Romelu Lukaku scored a brace before Marcus Rashford scored a last-gasp penalty against Gianluigi Buffon.
The penalty came about in acrimonious circumstances as VAR ruled that the ball had hit Kimpembe’s arm.
Ole Gunnar Solskjaer has emerged as a miracle worked as a result and is now odds-on to land the full-time vacancy.
But the man he replaced has had his say over United’s incredible result and has revealed who he wants his former side to take on.
Mourinho has been working for Russian programme RT.
And when asked what his preferred tie would be, he said: “I would like English teams to play against each other, without any kind of preference.
“But I would do two matches between English teams, which would mean two teams would be in the semi-finals.
“I think if the draw gives something like Manchester City versus Manchester United, or Tottenham against Liverpool, for example, I think would be absolutely fantastic matches.
“My second choice would be not by tactical or emotional reasons but by what I think would be fantastic extra motivation I would do Ajax versus Porto, as that would mean one of them reach the semi-finals.
“They are doing so, so well during the competition that I think it would be amazing for one of them.
“It would be amazing for Portugal as a country, Netherlands as a country, to have a team in the semi-final.
“I wouldn’t like Juventus against Barcelona because I think it would be something really special Barcelona against Juventus in a possible final or semi-final.
“Two great teams that are not being successful in the Champions League for a few years, of course Juventus so much more than Barcelona.
“And led by two big players Cristiano [Ronaldo] and [Lionel] Messi is something I wouldn’t waste on a quarter-final, I would wait a little bit more.”
