Arsenal may look to take advantage of the growing tension between Jose Mourinho and Iker Casillas by offering the Spanish goalkeeper a route out of Real Madrid.

The long-time Madrid number one was recently dropped from the first team by Mourinho despite being the club captain and consistently being recognised as one of the finest goalkeepers in world football.

Casillas was left out before Christmas as Madrid lost 3-2 to Malaga before once again finding himself on the bench at the weekend against Real Sociedad. However, he was soon called into action when Antonio Adan received a red card just five minutes into the game and helped the club achieve a 4-3 win.

Spanish newspaper Marca has reported that Arsenal are keeping a close eye on the situation at the Bernebeu and may attempt to offer Casillas a chance to test himself in the Premier League.

The 31-year-old has spent his entire playing career with Real Madrid and has featured more than 600 times for the club since making his debut all the way back 1999 when he became the youngest goalkeeper to ever play in a Champions League final.

As well as numerous league titles, Casillas has won the Champions League on two occasions; the Spanish Cup once and the UEFA Super Cup. His achievements for Spain are equally impressive as he has two European Championship's to his name and one World Cup.

Marca believe that Arsenal boss Arsene Wenger is unhappy with his current options and will attempt to move for Casillas who could be replaced at Real Madrid by Manchester United goalkeeper David de Gea.

There is growing belief that Real will look to sign the former Atletico Madrid stopper who has been earmarked as a potential successor to Casilla for the Spanish national side.

Arsenal have certainly failed to land a true first choice keeper and this season have used a number of options with Wojciech Sczczesny, Vito Mannone and Damian Martinez all handed the chance to make the number one shirt their own.

Nevertheless, despite Casillas' clash with Mourinho, it will be incredibly difficult to persuade the keeper to leave the club he supported as a boy and with whom he has enjoyed so much success.
