Abou Diaby
A player whose footballing style and quality evoked comparisons to fellow Frenchman Patrick Viera; it was surely disheartening to see Diaby's career being ravaged by injuries.
The towering central midfielder could make only 124 appearances for Arsenal in the 9 years that he spent at the club. Diaby suffered a severe ankle fracture early in his Arsenal career that many have said paved the way for future injuries and ruined his career.
Surely enough Diaby has been massively unlucky with injuries and has been known to have had suffered from nearly every injury in the book. He never could go on a decent playing run at Arsenal and was regularly injured throughout his playing career.
An eye-catching enforcer in midfield who could attack as well as he could defend, many have wondered what could have been had it not been for his injuries. Diaby was released by Arsenal in June 2015, and after featuring a bit for Marseilles is currently a free agent.
