#4 David Ospina

Ospina arrived at Arsenal on the back of an excellent 2014 FIFA World Cup, where he helped his national team reach the quarter-finals of the tournament. The Nice shot-stopper was expected to challenge Wojciech Szczesny for the #1 shirt and the Colombian did well to make 23 appearances for the club in his first season.
However, the arrival of Petr Cech a season later changed the entire complexion of the story and ever since the 28-year-old has been restricted to a bit-part role. The occasional brain fades that Ospina suffers has not helped his case either, nor has his relatively short height.
It is clear that the Colombian is not central to Arsene Wenger’s plans and as such the club should consider selling him at the earliest to help facilitate the growth of Emiliano Martinez as Arsenal’s second-choice shot-stopper.
