That is what you call 'taking one for the team' making sure they were not caught out on the counter-attack.
82. A long ball forward finds Sarr but as he takes it under his spell the flag goes up for offside.

Anyone in Selhurst Park would have put their house on Eze scoring.

72. It The Eagles were to win this it really would be a smash and grab victory.
Apart from the double save from Onana, they have created little in terms of clear cut chances.
That said, as long as Eze is on the pitch he is more than capable to produce some magic.
He plays the ball to Sarr who gives it back to him with the goal at his mercy.
Unbelievably, he side-foots it wide of the target.
What a chance.

Henderson is also booked for making his feelings known to the referee.
62. United are turning the screw once again.
Garnacho tries a curling effort from a wide position but once again Henderson makes the save.
He is proving to a thorn in the Red Devils' side today.
Martinez jumps into a challenge two-footed and is shown a yellow card.
Dreadful tackle.
60. It is almost like ten Hag was reading this.
Rashford has his top off and is ready to join the action.
He has scored three goals in his last two games and will have a point to prove as he no doubt was not pleased to be left out of the starting line-up.
58. One thing this game has shown today is that Zirkzee is certainly not the answer to Man Utd's striker crisis.
You feel it won't be long before ten Hag makes some changes.
They have both Rashford and Hojlund on the bench who could replace the Dutchman.
56. The longer Man Utd go without scoring you wonder whether they will get hit with the sucker punch in this game.
Looking at the stats, they have dominated possession and chances.
As we all know, rarely do you get points for this and the Premier League can be a cruel mistress if you are not clinical.
54. Big chance for the visitors.
Zirkzee knocks the ball down to Fernandes who tries a first-time shot from the edge of the box on the outside of his right foot.
So often we see him score from such a chance but on this occasion he sends it wide of the target, but not by much.
