Expert view: United's fringe players prove their worth to Jose Mourinho
ESPN FC's Mark Ogden argues that United's Eric Bailly, Marcos Rojo, Matteo Darmian and Diogo Dalot were able to stake their claim against Arsenal.
"Mourinho has not hidden his disdain for Man United's defensive options this season, with the quality of his defenders being an issue that the manager has raised more than once. With injury and suspensions biting hard at Old Trafford, Mourinho had no option but to turn to the out-of-favour Eric Bailly, Marcos Rojo and Matteo Darmian against Arsenal."
Time to shine
"Rojo has missed the majority of this season through injury, but even fit, the Argentine has been way down the pecking order. Wednesday saw his first appearance of the season for United, while Bailly has started only five games in all competitions. At left-back, Darmian was making only his third appearance in all competitions after being told by Mourinho that he could leave during the summer."
"Summer signing Diogo Dalot has seen his progress halted by injury and the young Portuguese was making only his fourth appearance. Dalot looks a star in the making at right-back with his strength, pace and attacking adventure, but Rojo, Bailly and Darmian face an uncertain future."
Good news for Mourinho
"Bailly did enough in this game to suggest he warrants more opportunities, while Rojo also suggested he can play a role once fully fit, despite the lapse in concentration that led to Arsenal's second goal. Darmian has never seemed comfortable or convincing at United, but he didn't harm his case for more opportunities off the back of Wednesday's game."
