Cape Town - Iker Casillas' future at Real Madrid is in jeopardy with the continuous speculation that David De Gea is set to join Los Blancos.
David De Gea's imminent arrival in Madrid could spell the end of Casillas' reign as the ten-time Champions League winner's number one goalkeeper.
According to Evening Standard, Arsene Wenger is keeping tabs on Casillas' situation at Real Madrid.
Arsenal are reportedly on the lookout for a new goalkeeper to provide competition to David Ospina and Wojciech Szczesny.
While earlier reports suggest an Arsenal move for Chelsea's Petr Cech was a "done deal", speculation continues to mount that Casillas could turn out for Arsene Wenger's side when the 2015/16 season starts on August 8.
Casillas made his first-team debut for Real in September 1999 and has made over 720 appearances for Real Madrid in 16 seasons with the club. The 34-year-old goalkeeper has won a host of trophies including three Champions League crowns and five La Liga titles.
