Celtic must make a ruthless decision on Odsonne Edouard's long-term future at the club and sell him in the January transfer window.

What's the story?

Reports over the summer suggested that Premier League sides like Arsenal were interested in signing him, but a deal failed to materialise before the end of the deadline.

Since then, Neil Lennon's side have been unable to tie down Edouard to a new contract to stay at Celtic Park, and now Football Insider have revealed that the Frenchman has "switched agents in a development that is set to have a massive bearing on his Celtic future".

Celtic must sell

With 11 goals in 23 games this season, Edouard certainly hasn't been awful at all for the Hoops, but there's been a drop-off in his performances.

Former Scotland international, Alan Hutton, said earlier last month: "We had all the talks about Edouard at the start of season wanting to leave – has his head been on it? Has he been the same player that he was last year? No.

"Whether he’s got someone in his ear saying: ‘Play your way, do your thing up until January or the summer and then we’ll move you on,’ I don’t know if those conversations have happened. He’s a massive asset, he will be worth a lot of money but it looks like he wants to move on."

The longer Edouard stays at Celtic without his long-term future being resolved, the bigger the headache becomes for Lennon. Is the £13.5m-rated Frenchman someone the Bhoys can rely upon going forward? Or will he be looking for a quick exit the moment an offer comes in?

That uncertainty is bound to have an impact on how he plays on the pitch, no matter how good someone is at blocking out the outside noise. Celtic could move on for the better by calling time on Edouard's stay at the club.
