What a performance. To think he was just 19 years old at the time is just astonishing.

"He played a fantastic game against us [in 2011]. Let's not forget he was just 20 years old [He was 19]. It's just a shame he got injured so many times over the past two years," Xavi told Sport, per Tribuna.

Wilshere produced a brilliant answer when recently asked about who he learned the most from in that game.

"Couldn't learn much, they all spent the night in my pocket", he joked.

Unfortunately, Wilshere's career since then has taken a downturn.

He has suffered from numerous injuries and now plays for Bournemouth in the Championship.

The Englishman has still had a decent career, but it could have been so much better had he not sustained so many injuries.
