While he boasted a six-pack during his playing days, Ozil was always rather scrawny and one of his biggest weaknesses was his physicality.

Since retiring earlier this year the former Germany international has been a regular at the gym – and he has bulked up as a result.

Ozil’s trainer has shared several clips of him hard at work, with the 35-year-old going through a range of exercises from push-ups to bicep curls.

The former midfielder flexed his biceps on a cable machine and curled dumbells to increase his muscles.

In another Instagram post Ozil flashed his six-pack as he beamed at the camera.

Fans were impressed with his transformation and suggested he ought to come out of retirement.

One said: “Bro needs to come out of retirement play for like three or four more years.”

Another added: “Ozil start playing football again😭”
