Jack Grealish showed off his ripped physique as he began training early while on holiday in Greece.

He posted to his 5.1m followers on social media on Wednesday, with the caption: ‘Working in the heat,’ followed by a sun, running and football emoji – and it has already been liked more than 190,000 times.

The images show him striking a football on a sandy pitch under sunny blue skies, running across a grassy pitch at a training centre, volleying into an empty goal and posing in just his shorts, socks and boots.

Grealish is officially set to return to pre-season with City on Monday as Pep Guardiola’s side look to defend their Premier League title.

The 26-year-old had posted a similar set of training photos while holidaying on Greek island Santorini, with former Aston Villa team-mates Shay Given and Carlos Sanchez commenting to show their support.

Grealish flew to the capital city to train on his own at Athens-based champions Olympiacos’ complex.

He had earlier trained with a small local club on Santorini, who offered to move their under-10s camp to accommodate him.

The 23-cap international has spoken openly about the difficulties of adjusting to a much different style of football and the strict demands under Guardiola.

Grealish joined City from his boyhood club Aston Villa in a massive £100m deal last summer, becoming the most expensive English player ever and the sixth-most expensive of all time.
