Iker Casillas is going through a torrid time in his career, unable to get into the starting XI at Real Madrid, and the Spanish international admitted he just might say enough is enough and finally move on.

Casillas and Real Madrid are almost one and the same, and it is near unimaginable to think of the goalkeeper putting on the shirt of another club.

But as they say time waits for no man and with Diego Lopez looking like he has no plans to relinquish his No.1 role, Casillas, who joined Real as a nine-year-old, might just have to look for pastures anew with a switch possible in January.

"If a player isn't in the action then he starts to think about making a decision," the 32-year-old said. "I'm human and I'm a footballer. I haven't played for nine months now and it's the same for me. I'm not a robot.

"Of course I want to stay here and win more titles with Real Madrid. I've been here since I was little, but there will come a day in which I have to take a decision.

"As of now my decision is to stay and fight, to struggle and play every day. If I wasn't sure about it I would have told the president I wanted to leave in September.

"That being said, if in three months things haven't changed and you ask me the same question, well maybe I'll be thinking about leaving."

Real manager Carlo Ancelotti has employed a policy of playing Lopez in the La Liga, with Casillas only given opportunities in the Champions League.

Casillas, though, wants to be playing more often to ensure he does not lose his place in the Spain national team.

"Psychologically, you have to take the positive out of this," Casillas said. "Ancelotti's decision is the latest challenge, an abnormal situation and I want to win confidence. I will fight to get back into the starting 11. I want to play more. To play for your national team you have to be playing for your club."

Casillas has been heavily linked with a move to the English Premier League, with Arsenal thought to be the most keen.

Wojciech Szczesny has been in good form for the Gunners this season, but Arsene Wenger is thought to be open to bringing in an experienced goalkeeper, and they don't come more experienced than Casillas.

Manchester City, with Joe Hart looking a little wobbly, might also show an interest, but it is unlikely that the likes of Manchester United, Chelsea or Liverpool will be keen on a transfer.
