JACK GREALISH says he is a good-hearted person who does “stupid stuff”, which explains why the forward goes from talking about making a boy feel like a king with his celebration to expressing remorse about his dig at Miguel Almiron.

Last year the home-grown Aston Villa star became the most expensive English player in history, continuing the fascinating career path of a 27-year-old whose life has played out in the public eye.

Grealish does not shy away from his mistakes and embraces the pressure that comes with playing for reigning Premier League champions Manchester City and attempting to help England to World Cup glory.

Brought on by Gareth Southgate in every game in Qatar so far, the skilful forward scored a tap-in against Iran which allowed him to fulfil a promise to Finlay Fisher, a City-supporting schoolboy with cerebral palsy.

“That’s natural - I don’t do that for any clout or whatever,” Grealish said of the ‘wave arms’ celebration he said he would do for the 11-year-old.

“I do that because that’s what I feel like I’m good at sometimes. Because I can relate to it with my little sister (Hollie, who also has cerebral palsy), it was a nice thing for him as well.

“Because it was so popular, it’s nice for him because he’ll go back to school and he’ll probably be like quite popular. That was just something that came naturally.

“I think it ended up being so nice and quite emotional actually. That’s just the way I’ve been brought up. I know I’ve been brought up well.

“I’ve got a good heart, I think I have. Obviously I’ve done stupid stuff in my life but I think everything that I do good is from my heart.”

Grealish’s family have been in Qatar, with dad Kevin donning a Union Jack waistcoat and bow tie that “looks like something from the market” at games that visually-impaired sister Hollie supports him at, according to the City player.

“She gets it but she obviously can’t watch the game and stuff, so she just sits there on her iPad,” he said.

“She’s addicted to Coronation Street, so she watches Coronation Street from 1998. Kirk on there is about ten years old. He’s about 40 now, isn’t he?”

Grealish laughs as he speaks warmly about family and living his dream to the fullest, meaning he is often the last person to leave training – and sometimes the bar.

The 27-year-old’s antics as City celebrated May’s Premier League title win only highlighted that as the sozzled star went from amusing fans to poking fun at Newcastle’s Almiron.

Grealish likened Riyad Mahrez’s ineffective performance on the final day to the Paraguayan in a video he did not realise was public and quickly went viral.

“When I said earlier that sometimes I do stupid stuff, that was one,” Grealish said. “I regret that.

“I swear, I’m actually buzzing the way he’s reacted. He said something about me in the interview the other day, he wished me the best.

“I thought, ‘What a guy, man’ because if that was me and somebody had said that about me, I’d have probably been the other way and been like ‘f*** it’.”

Grealish contacted former Villa team-mate Matt Targett to apologise to Almiron, who is in impressive form.

“I thought it was just private but even in private I shouldn’t have said it because he’s a fellow professional,” he said. “I’m actually buzzing for him. I’ve had a lot of stick off the Newcastle fans and rightly so.”
