Sky Sports understands a number of clubs are tracking Leyton Orient midfielder Dean Cox.
Cox has started the new season in fine form, scoring three goals in four games to help Orient make a perfect start to the campaign.
The 26-year-old's performances have not gone unnoticed higher up the football pyramid with several Championship clubs keeping tabs on him.
Cox has established himself as a key player at Orient since arriving in 2010 from Brighton and is a big fans' favourite at the Matchroom Stadium.
Orient would be loath to lose Cox, but they could face a fight to fend off his suitors if they come calling before the close of the transfer window.
