#2 Jack Wilshere
Wilshere was one of Wenger's most trusted players. Whenever fit, the Englishman was a sureshot to make it into the starting eleven. Last season, he played 40 matches in all competitions. It was the most number of matches he has played in the last five seasons. After the end of the 2013/14 season, Wilshere had never played more than 30 games each season.
Similar to Diaby, the 27-year-old has suffered numerous injuries throughout his career. He spent the majority of his youth career training with Arsenal's youth academy and gradually moved up the ranks. In 2008, he made his first team debut at the age of 16. Subsequently, he made his international debut for the Three Lions back in 2010 at the age of 18. Everyone had great expectations of him, but he never quite made it.
The midfielder is strong and has a keen eye for key passes. During his years with the Gunners, he has scored some wonderful and powerful goals, and also produce numerous assists for his team-mates. Previously, Wenger had tipped him to be Arsenal's captain after Per Mertesacker's retirement. He displayed leadership skills at the heart of all the attacking action and had the experience. However, Wilshere failed to renew his contract with the club.
Now over at West Ham, his first season with the club has yet again been filled with weeks on the treatment table. At one point, it was rumoured at his season could be over following an ankle injury. Manuel Pellegrini has since given an update that the former Arsenal man could be due for a return.
