England's Jack Grealish

England’s warm-up matches have been marred by a section of supporters booing when players have taken a knee prior to kick-off in a gesture of anti-racism.

But Villa skipper Grealish is hopeful there will be a positive atmosphere to spur the Three Lions on when they begin their campaign against Croatia at Wembley on Sunday.

“I can’t explain enough (what it would mean), if we have that positive atmosphere,” he said. “I was speaking to Declan Rice about the Three Lions song and showed him a video.

“Stuff like that gets me pumped up and makes me happy and I know it does for a lot of the other lads as well.

“That positive atmosphere, singing, which I am sure we will get. You only have to look at videos from Russia 2018 and you will see plenty. The nation coming together will only spur us on and make us perform better.”
