Oxford United chairman Kelvin Thomas says he is not looking to sell captain and top scorer James Constable.The 26-year-old has scored nine goals this season - including the winner in Saturday's 2-1 victory over Barnet. [LNB]Thomas told BBC Oxford: "I think we're OK with Beano [Constable] and we're not looking to sell our players. [LNB]"You never say never in this game, but they'd have to come in with some serious money for Constable - he's proved himself now." [LNB]Thomas added: "He loves to score goals. That's what he's here for and you have to give him credit." [LNB]The goal on Saturday was Constable's first since October, following an illness which has led to him being substitute for the last four league games.
