Arsenal midfielder Jack Wilshere has said his new gluten-free diet has put him in the best shape of his career.

Wilshere starred in the thrilling 2-2 draw at home to Chelsea on Wednesday, opening the scoring with a thumping finish.

Eden Hazard’s penalty and a late goal from Marcos Alonso put Chelsea in front, before Hector Bellerin added the final twist in stoppage time.

Wilshere produced another industrious display in central midfield, his sixth consecutive 90 minutes in the Premier League, and told the London Evening Standard: “I have been dairy and gluten-free now for six weeks.

“I feel that I look better, I have certainly lost a bit of weight, and am leaner. I am probably fitter as well. I feel sharper and quicker on the pitch. I feel like I can last longer.

“For example, at the end of the Chelsea game when we scored the second goal, I felt: ‘Come on, we can go on again here.’ I was pressing them and felt good.

“I know my body well, I know the right foods to eat and the best way to recover. I’m also getting the right amount of sleep.

“I’ve learned that over the years and I think I’m in the best shape I have ever been.”

Wilshere told Sky Sports after the match there had been “no progress” in talks on an extension to his Arsenal contract, which expires at the end of the season.

Meanwhile, Arsenal defender Shkodran Mustafi said he was frustrated by the Chelsea result despite his side’s late leveller.

“It feels more like a defeat than like a winning equaliser,” he told the club’s official website.

“Unfortunately it was not too entertaining for us. We were dominant in the first half and I think we had the first opportunities.”

Arsenal now turn their attention to an FA Cup third-round tie at Nottingham Forest on Sunday.
