Wigan boss Martinez reveals he wanted Real Madrid keeper Adan
Martinez fancied Adan before landing Ali Al-Habsi from Bolton Wanderers.
"Antonio was playing in the Real Madrid B side at the time and we had a look at him before we signed Ali Al-Habsi," said Martinez.
"He was in a long-term contract at Real and he had to be allowed out on loan.
"He wasn't going to be in the first team and he wanted to come to us but Real wouldn't let him leave."
