DEBUTANT Joshua Zirkzee was the hero for Manchester United in an evening where their new guns showed what they are all about.The Dutchman had to remain patient for his opportunity but he took it brilliantly once he came on the pitch.Zirkzee came on for Mason Mount on the hour mark and had been quiet up until his pivotal moment.Ten Hag will take positives from the display and it was his astute sub which led to the winner as his side got their season off to a flyer.Here is how SunSport’s Phil Thomas rated the Red Devils display…Andre Onana – 6Made an outstanding early tip over from Kenny Tete and was rarely seriously troubled beyond that.Noussair Mazraoui – 7A pretty impressive debut from the Moroccan. Looks assured on the ball, gets forward in support and can put a foot in.Harry Maguire – 7Dominant and commanding in defence, but embarrassingly booked for diving at the other end. Really Harry, even you?Lisandro Martinez – 6Skinned by Adama Traore early. Showed all his defensive guile in how he handled him after that, and got back superbly to deny a breakaway goal.Diogo Dalot – 6Had his hands full dealing with Traore’s pace, but knocked in a couple of wicked curling crosses at the other end.Casemiro – 7Headed over then shot over, but two great passes put Fernandes clean through. Often looked United’s most likely source of a goal.Kobbie Mainoo – 8So crisp, so tidy, so rarely wastes a pass. Another near-flawless, if not exactly flair-packed, display from the youngster. Fizzed a shot just wide, too.Mason Mount – 5So desperate to do well, which earned him an early booking. Only Leno’s legs denied him the goal his effort deserved.Amad Diallo – 5Made one marvellous mazy run into the box, although the tumble to ground that followed wasn’t so impressive.Marcus Rashford – 6Still nowhere near the star of two years ago, but another step in the right direction at least. Some way to get yet, though.Bruno Fernandes – 7Fluffed two great chances, driving at keeper Leno’s legs twice when Casemiro put him through, but sprayed passes around and started the move for the winner.SubsAlejandro Garnacho (for Diallo, 60mins) – 6Put a spark in United when he came off the bench and teed up the winner.Joshua Zirkzee (for Mount, 60 mins) – 7The debut he dreamed of. Barely had a touch, but then fed the ball wide and stuck out his left foot to jab the winner.Matthijs de Ligt – (for Mazraoui, 81 mins) – 5Was only on for the last ten minutes and looked solid although he did not have too much to doJonny Evans (for Maguire, 81 mins) – 5Scott McTominay (for Mainoo, 84 mins) – 5
