Former English defender Stephen Warnock has backed Rashford to identify and cause trouble to Chelsea defender David Luiz.
“If I was Rashford I would be getting myself up against David Luiz,” Warnock told BBC Radio 5 live. “You know that defensively he (Luiz) can be a 10 or a three. That’s how his scale goes from one game to the next.
“There are not many better ball-playing centre-halves than him and if you want to play ‘Sarri-ball’ then he’s your ideal defender. But when you’re leaving yourself so bare at the back, often two-v-two, you can’t have him.
“When he was playing well in a three he had two out-and-out defenders playing with him in [Cesar]Azpilicueta and [Gary] Cahill. He was made to look great by them.
“And that is what is missing… that comfort blanket next to him. He’s got Rudiger next to him and doesn’t get that cover. United have to play at him and get down the side.”
“I think as a striker you feel like you will always get a chance against him,” Coyle said. “Just that lack of concentration and as a striker you would think I would have a chance against him.
“Given Chelsea have conceded some really soft goals of late, you still have Gary Cahill there, a top England international who hasn’t been playing games.”
