Injuries have heavily impacted the development of the 24-year-old in recent years and new surroundings have been deemed the ideal option to help him reach his once astronomical potential.
Looking to revive career

The youngster was soon hailed for big things and compared to many of the greatest central midfielders ever to play the game. However, Wilshere’s now well-renowned injury problems started in 2011 when he suffered a stress fracture and was ruled out for the whole of the 2011-12 season.
According to transfermarkt.co.uk, Wilshere has missed a staggering 154 competitive games for Arsenal in his seven years as a member of the first team.
Having recovered from his latest set-back in pre-season, Arsenal and Wilshere decided it was best to find a temporary spell away from the club. It is reported that 22 clubs tabled a deal for Wilshere with Crystal Palace the original frotrunners, followed by three top Serie A clubs. However, a move down south was deemed best for a player who is hoping to make up for lost time.

Since then, he has gone on to make another 33 appearances for the national team, although was not a part of Sam Allardyce's first squad, which was announced on Sunday evening.
