Swansea City midfielder Leon Britton has revealed Premier League club Wigan Athletic are interested in signing him.The 27-year-old, who is out of contract at the end of the season, is interested in a top-flight move to link up with former Swans boss Roberto Martinez. [LNB]"Obviously Roberto knows me well," Britton said. "It's always nice to know that he likes me as a player. [LNB]"He has made an inquiry to the club about my availability. I know the clubs have been talking." [LNB]The former Arsenal youngster is one of Swansea's longest-serving players after joining from West Ham United in 2003 - after a brief loan spell - as a teenager. [LNB]Britton, who roomed with Wigan boss Martinez when the pair were together at Swansea, is worth about £1.5m and would expect a big pay rise should he move to the Premier League. [LNB]The fans' favourite previously conceded he was "surprised and disappointed" that Paulo Sousa made public details of his contract negotiations. [LNB]The Swansea boss revealed Britton, who has made more than 300 appearances for the Welsh club, would become one of the best paid players in the club's history.[LNB] Leon will be sorely missed by the club especially now that we know he has spoken to Wigan friendlybigboytel The long-serving playmaker has been instrumental in transforming the club from a bottom division struggler to a team that is considered a Premier League promotion contender. [LNB]But Britton has a young daughter and has previously admitted he has been unsettled by the turmoil of his recent split with his daughter's mother who has moved back to his native London. [LNB]Martinez has already signed one-time Swans stars Jason Scotland and Jordi Gomez for Wigan and the Spaniard, who has previously stated Britton has Premier League quality, is interested in signing Britton. [LNB]"Obviously the chairman has talked about it now and there has been contact between the two clubs," Britton told the South Wales Evening Post. [LNB]"I know they have been talking and, with my contract situation, everyone knows I'm free to talk with other clubs. [LNB]"It's a difficult one for me. I am still here at Swansea, I am under contract and I am enjoying my football. [LNB]"I'd like to think my performances show I'm still fully committed even though these things are going on. But other than that I can't really say much about it until I am fully informed by the club. [LNB]"I certainly won't be disappointed if nothing happens. I am under contract at Swansea and my feelings towards the club haven't changed. [LNB]"I've still got five months on my contract and, before Wigan's interest came around, my thoughts were fully focused on being here until the end of the season. [LNB]"That is still the case and I am still a Swansea player. [LNB]"If something happens and the club agree a fee then you have to go from there. But, if not, I am fully committed to the club and trying to get Swansea in the Premier League." [LNB]Wigan manager Martinez hopes to bolster his squad before the transfer window closes on 1 February and Lactics midfielder Ben Watson, also a transfer target for Swansea's Welsh Championship rivals Cardiff, may be a makeweight in any deal.
