Why Marcus Rashford will be key if Man United are to spring an upset on Atletico Madrid: Ashley Young reveals how winger's Barcelona exploits can 'play into Michael Carrick's hands'

That is the view of former Manchester United attacker Ashley Young , who believes Rashford's pace could be the difference between winning and losing in Madrid on Tuesday night. Rashford is yet to get a goal or assist since coming back into the fold at United this season and started the weekend's draw against Tottenham on the bench. But he is the biggest pace threat United have and his knowledge of Spanish football, having been on loan at Barcelona last season, is another feather in his cap in Young's view.
