Manchester United have added a fourth star to their list of 'unsellable' players following Saturday's FA Cup triumph over derby rivals Man City.
There are many issues to address at Old Trafford following the end of the season with manager Erik ten Hag's future top of the pile, while recruitment is another top priority.
Ten Hag may have secured himself a career lifeline by guiding United to their best performance of the season at Wembley and four of his players are now regarded as untouchable by the club, as reported by the Manchester Evening News.
A dreadful Premier League campaign - that saw United suffer their worst-ever finish in the competition - has led to questions being asked over what players will still be at the club next season.
United are preparing for a mass fire sale over the summer, with Anthony Martial confirming his exit on Monday evening, and other stars expected to follow him out the door.

United have already named a trio of youngsters as not for sale in the summer transfer window
FA Cup final goalscorers Alejandro Garnacho and Kobbie Mainoo are regarded as two players not available for purchase, while interest in Rasmus Hojlund will also be dismissed.
Now it has been claimed that goalkeeper Andre Onana won't be allowed to leave United after impressing in the second-half of the season during his debut year in England.
The Cameroonian struggled to settle in Manchester after completing a £47.1m transfer from Inter Milan last summer and was at threat of losing his starting place.
Unforgiving mistakes in the Champions League were one of the highlighted reasons for United's shock group stage exit, while he also looked void of confidence in the Premier League.
However, Onana eventually began to demonstrate his shot-stopping capabilities and produced another largely impressive performance in the weekend's trophy triumph over Man City, despite conceding a tame effort from Jeremy Doku.

Speaking to MUTV at the start of May, Onana revealed how he struggled to adjust to life in England's north-west but is now happy in his surroundings.
'When I look back now, I'm just smiling because it was a big lesson for me. But in the beginning I was like, ‘Wow, did I make the right choice?' he said.
'But I'm definitely 100 per cent sure I made the right choice because Manchester United is the bigger club in this country, it's one of the biggest clubs in the world.
'Who would say no to come to play for this beautiful club?.
