2) Iker Casillas
Although Arsenal have already signed a new goalkeeper in David Ospina, Arsene Wenger is also reported to have held talks over the possible signing of Real Madrid’s Iker Casillas. The veteran Spanish shot-stopper is out of favour at the Bernabeu with the signing of Keylor Navas, and could be a useful short-term option in goal for the Gunners if he can regain anything like his best form. Manchester City have also been linked with him in recent times.
