Manchester United winger Ashley Young is unsure how England players will react if they're subject to racist abuse.

UEFA have vowed to adopt a "zero-tolerance" approach to racism at this summer's finals, with referees having the power to abandon games if necessary.

But UEFA president Michel Platini also warned on Wednesday that any player who walked off the pitch in protest at racist abuse would be yellow-carded.

Asked if England might walk off, Young said: "Who knows? Hopefully, it doesn't happen and UEFA deal with it before a decision has to be made.

"You don't want to put up with things like that but it is for UEFA to deal with.

"I am sure they would do in the right way. We will see what happens.

"If it happens, I am not too sure what we would do."
