3 – Keylor Navas
Arsenal are said to be on alert for a replacement to Petr Cech, who is now 35 and his performances are dropping in quality. 30-year-old Navas is said to be feeling under-appreciated at Madrid under Perez and could be tempted by a new challenge in the Premier League, with reports in Spain linking Arsenal and Liverpool with a move for the Costa Rican. If David de Gea finally makes his move to Madrid, it could pave the way for Navas to leave.
