Bardsley – a former United trainee – was kicked by Rashford as the pair tangled off-the-ball at Turf Moor.
Rashford's first football coach Dave Horrocks, the development officer at Manchester junior club Fletcher Moss Rangers, is quoted by The Sun: “Phil Bardsley is one of the biggest, two-faced 'herberts' going.
“He is ex-United player, who was upset Sir Alex Ferguson got rid of him because he wasn't good enough.
“Now all he wants to do against United is to kick players.
“Throughout Marcus's career, he learned all along the way. He has been prepared for everything and taken every opportunity that has come his way.
“This for me will be the perfect lesson to learn from and go out and realise how easy it is to get conned. Because I think he was conned and fell for the three-card trick.
“As a baby, all he wanted to do was play football. He wasn't confrontational. He doesn't even answer his mum back, let alone anybody else.
“As far our young man is concerned, he doesn't have that sort of streak in him.
“But I would like him at some stage to have that because that's what is missing from him. Considering he is from the streets, he is quite a timid, quiet boy."
