Leyton Orient winger Dean Cox has admitted his time at the club may be up ahead of next month's transfer window.

Cox started today's 2-0 defeat at Barnsley on the bench and was unable to help the O's rescue the game after coming on during the second half.

The former Brighton winger scored in May's play-off final defeat to Rotherham but is now part of a team joint bottom of League One.

Cox, who is working under his fourth manager of the season, said: "It's a big change and we might have to review it.

"Obviously it's a bit difficult at the moment with what's going on. I've been here five years now and maybe my time's up."

New manager Fabio Liverani is likely to be active in the January transfer window and Cox is uncertain how many players will arrive and depart Brisbane Road in the new year. 

Cox said: "I don't know if I'm honest. Obviously there's a window coming up. Does he want everyone staying? Is he bringing in different players? I don't know.

"He's obviously got his own ideas and we'll see what avenue he goes down. But we hope we start picking up some results."
