Jose Mourinho walks out of Man Utd news conference after 11 seconds

And Red Devils defender Jones has sounded a warning against complacency ahead of the “huge” match.

Last year, United had six pre-season friendlies including the Community Shield against Leicester City, but as we saw during his time at Chelsea, Mourinho puts a huge emphasis on the quantity of games that his players play in pre-season.

Few players are as valuable to Manchester United as Ander Herrera. Win, and it is a double-winning campaign in which they assured Champions League qualification.

The shop window of the Europa League final in Stockholm means Ajax can expect added interest in a bevy of players already earmarked for the exit door at lucrative profit for the Amsterdam club.

A good half for Mourinho ended in worrying fashion, however, when Eric Bailly – who is suspended for the Europa League final – made a full-blooded challenge on Zaha as he threatened the United goal and immediately fell to the ground clutching his knee. “We have the final, we have to make sure we win, and then I have the [under-21s] Euros, and I come back for preseason and [have to] work hard and give everything, and we will see step by step”.

‘We’d watch the Champions League and we’d be wishing next season we are there.

“He was true to his word. I really feel sorry for him because I think he’s shown outstanding qualities”.

While the United players were doing their customary end-of-season lap of honour, Mourinho have MUTV a very short interview before heading in to meet the press.

United’s performance belied their tender average age of 22 years 284 days, with Harrop marking his first appearance with a superb effort that kicked off a surprisingly comfortable 2-0 win against Palace.

It was a game that Harrop, in particular, will never forget thanks to his debut goal which followed a hat-trick he scored for United’s under-23s in a victory against Tottenham at Old Trafford on Monday.

There was no chance to ask Mourinho about his compatriot’s display as the United boss zoomed out of the post-match press conference, but recently he said Pereira would be “the best Portuguese goalkeeper of the next generation”.

The 16-year-old Gomes became the youngest debutant since Duncan Edwards and the first millennial to appear in the top-flight, and Harrop stated that Sunday’s clash is a big day for the club’s academy.

“They don’t use Pogba where he should be playing – he’s not a holding midfielder”.
