Celtic have stepped up plans to cash in on Scott Sinclair in January by placing him in the “shop window”, Football Insider has learned.

Sinclair has been frozen out at Parkhead for virtually the entirety of Neil Lennon’s second spell at the club and slipped well down the pecking order for attacking places.

A Celtic source has told Football Insider that Sinclair’s starting role in last night’s 2-0 Europa League defeat to Cluj was driven by Lennon’s desire to make clubs aware he is fit and playing.

The winger, 30, played the full 90 minutes for what was effectively a Hoops ‘B’ team, barring centre-back Christopher Jullien and fit-again Boli Bolingoli-Mbombo.

Privately, Celtic figures believe Sinclair is the most likely to go of the senior players in January and the club will sell him for the right price.

That is believed to be around £1million for a player who is out of contract next summer and has made just seven appearances all season, six of which have been as a substitute.

Sinclair made his first start of the campaign last night for what was a dead rubber as Celtic had already qualified for the Europa League knockout stages as group leaders.

The high-earning attacker, whose deal is worth more than £30,000-a-week, is eyeing the January window to provide a route back south of the border.

He is behind not only first choice Mohamed Elyounoussi in the battle for the left-wing role he once made his own at Celtic, but also Mikey Johnson, Jonny Hayes, Lewis Morgan and the versatile Ryan Christie.
