Arsenal are closing in on a mega deal for Iker Casillas, with the English Premier League club reportedly putting forward an offer that the Spanish international goalkeeper cannot refuse.

Arsene Wenger has admitted he will definitely bring in a goalkeeper to the Emirates during the summer transfer window to compete with current number one Wojciech Szczesny, with the manager having to dip into the transfer market following the departure of Lukasz Fabianski to Swansea City.

Reports have suggested the Gunners have pretty much signed David Ospina from Nice, with the club agreeing on a £3.2 million fee with the French club as well as personal terms with the player.

It is believed Ospina will be revealed as an Arsenal player once the club returns from their preseason trip to New York.

However, according to Spanish newspaper Sport, a Barcelona-based newspaper, it should not be forgotten, Arsenal are, in fact, set to sign Real Madrid legend Casillas.

The report suggests Wenger has offered the 33-year-old goalkeeper a lucrative five-year contract worth more than £100,000 a week, and Casillas has made up his mind to move to the English Premier League.

All that remains for the deal to be completed is Casillas agreeing with Real Madrid to allow him to leave on a free transfer as Arsenal are reportedly not ready to offer a fee.

Casillas' future is up in the air with Keylor Navas set to complete a move to the Bernabeu. Diego Lopez has been first choice at Real Madrid for the last season and a half, and if he refuses a move to Monaco, then Casillas stands the chance of being third-choice at Real.

Arsenal have previously been linked with a move for Casillas, who had a horror World Cup with Spain, but with the Ospina move looking like a done deal, it does look unlikely that Wenger will bring in a third goalkeeper to the club.

Of course, there is a chance that Ospina has not as good as sealed his transfer to Arsenal, even if Nice have reportedly completed a move for his replacement by signing Algeria international goalkeeper Rais M'Bolhi.

However, that does look unlikely, making the Casillas switch to Arsenal even more improbable. But then, stranger things have happened.
