Central Coast are that much closer to losing their star gloveman Mathew Ryan with English Championship club Hull City offering the talented youngster a lucrative deal.Ryan looks set to be snapped up in the January transfer window with Mariners chairman Peter Turnbull confirming several clubs had expressed interest in securing the 20-year-old's services.Ryan, who is yet to make his on-field debut for the Socceroos, was part of the squad that travelled to South Korea and beat the hosts 2-1 in a friendly in Hwaseong on Wednesday.Now in his third season in the A-League, he has been catching the attention of overseas clubs since winning the Goalkeeper of the Year award last season.Ryan is out of contract at the end of the season, and the Mariners are resigned to losing him sooner or later.It's believed Hull have offered Ryan a lucrative three-year contract, while the Mariners can expect to receive a substantial transfer fee."It is disappointing that these private commercial discussions are in the public arena, but I can confirm Hull City are one of a number of clubs to have expressed an interest in signing Mathew Ryan in January," Turnbull said."Hull have tabled an offer for Mat as a result of his good form in the A-League, selection for the Socceroos as well as his undoubted potential."Negotiations with Hull are still at an early stage however we will continue to talk with them and several other clubs over the coming weeks in order to arrive at the best possible outcome for Central Coast Mariners FC and Mathew."Ryan trialled with English Premier League sides Tottenham Hotspur and West Bromwich Albion just before the start of the season.Hull, who currently have Ben Amos between the posts, are currently fourth in the Championship table and on course for a return to the EPL after three seasons in the second-tier.
