Cesc Fabregas believes that Jack Wilsch could have made golden days in Barcelona or Real Madrid and had the potential to become an England legend.
Wilshere made rapid progress since moving to Arsenal under Arsene Wenger in 2008.
He quickly made his way to the Frenchman starting line up and made a place for himself in the England national team.
He has proven himself well in the Champions League and the Premier League, and his most notable performance is his brilliant display in the 2-1 win over Barcelona in the 2011 Round of 16.
However, he went through a period of a decline very quickly. After leaving Emirates, Wilshere, who was considered a free agent, joined West Ham, and Fabregas is upset by the bitter events that befell his former teammate.
He told the Daily Mail: "Jack was such a good talent, one of the most talented players I've ever played with," the former Gunners midfielder toldThe Daily Mail
"He was just 16 when he first came to train with us and I was like 'wow this guy is good, strong, sharp'. It's a big shame what has happened to him, I feel sorry because he could have been a proper English legend of the game.
"We always talk about how British players would adapt to teams in Europe - I always believed that Jack was one of the few Brits who could have made it big time at Real Madrid or Barcelona.
"Same with Aaron Ramsey and Gareth Bale. These guys are so talented, without injuries they could have done much more."
