Amad Diallo's brace leads Manchester United to first Europa League victory of the season

United had tied their last three Europa League matches, but Diallo's skillful header from a cross by Bruno Fernandes early in the second half broke the streak and gave Van Nistelrooy's team the lead.

With both sides searching for their first win the Greek visitors to Old Trafford had their chances to take something from the game and United keeper Andre Onana had to tip over a shot from Mady Camara in the first half.

PAOK had an excellent opportunity to equalise in the 64th minute but the unmarked Taril Tissoudali could not get enough power in his shot from close range to beat Onana, and Diallo made sure of victory 13 minutes from time.

This time he did it all alone, dispossessing Baba Rahman and holding off the defender’s challenge to make his way to the edge of the area before unleashing a curling shot which took a slight deflection on its way into the far corner.

Van Nistelrooy, who will shortly make way for new manager Ruben Amorim, replaced the sacked Ten Hag 10 days ago and is unbeaten in his three games in charge.

United have six points in the Europa League standings.
