Perez undergoes West Ham medical as Ospina set for Besiktas talks

Arsenal are in discussions over the sale of two of their fringe players, with Lucas Perez and David Ospina both potentially leaving the club in the coming days.

Goal understands that Perez has undergone a medical at West Ham, while Ospina will hold talks with Turkish giants Besiktas over joining them before the summer transfer window closes.

Perez, 29, had returned to Arsenal following a season-long loan at former club Deportivo La Coruna in 2017-18, where he scored nine goals in 37 appearances.

Perez moved back to Deportivo on loan after initially joining the Gunners in 2016 in a move reportedly worth around £17m ($22m).

But Perez found playing time hard to come by in his lone season at the Emirates, making just 11 Premier League appearances and scoring one goal in the league. 

New Hammers manager Manuel Pellegrini has been busy since his May appointment, and Perez would represent his ninth signing since taking charge. 

Ospina, meanwhile, has looked likely to depart since the Gunners signed Bernd Leno from Bayer Leverkusen in June. 

With Leno and Petr Cech set to battle for the No.1 role, the Colombia international has been pushed down to third on Arsenal's depth chart.
