Jack Grealish works up a sweat as he shares topless picture while on holiday with girlfriend Sasha Attwood

Grealish was a shock omission by the Three Lions boss as he was one of seven players cut ahead of their final warm-up friendly against Iceland.

However, the ex-Aston Villa man did not let his disappointment get in the way of wishing the players well for their clash with Serbia on Sunday.

The popular attacker – who has also enjoyed a holiday in Dubai in recent weeks – took to Instagram to post: “Good luck to the lads.”

Following England’s 1-0 win, Grealish took a picture of the Sardinia sea and added the caption: “Perfect for a morning run.”

A short while later, he then added a Boomerang of him blowing his cheeks out as he was seen topless while sweating from his workout in the 24-degree heat on his well-earned “break”.

Sasha, who has been dating Grealish since the pair were teenagers at school, also shared a snap of her drink by the pool.

The Man City man endured a difficult season at the Etihad, scoring just three goals and providing three assists in 36 appearances.

Grealish’s inconsistent form saw him drop below the likes of Eberechi Eze, Anthony Gordon and Jarrod Bowen in the England ranks.

After deciding to drop Grealish, Southgate explained the decision by saying: “I have just delivered a really difficult conversation to a lad who is devastated.

“I think the world of him as a kid.

“It certainly doesn’t get any easier. You put yourself in the shoes of a player, a parent. You understand that for these players this is a devastating moment.

“We knew we had a couple of really difficult days coming up.”
