Speaking ahead of Sunday's Old Firm, former Celtic striker Frank McAvennie believes Boli Bolingoli should be sold after hearing that he is underperforming at Lennoxtown.

The Lowdown: Bolingoli at Lennoxtown

The 26-year-old was a peripheral figure for the Hoops earlier in the season, making just two starts in the Scottish Premiership overall.

Bolingoli was then loaned out to Russian side FC Ufa in February, effectively confirming that Ange Postecoglou doesn't see him as a significant part of his squad moving forward, before that spell ended prematurely.

Since then, he has been training alone, as reported earlier this month, in what has become a strange situation for the versatile Belgian.

The Latest: McAvennie calls for summer sale

Speaking to Football Insider before the Old Firm, McAvennie suggested that there are issues with Bolingoli's attitude at Lennoxtown and that he should be moved on in the summer:

"He came in at the start of the season and I thought he did quite well to be fair. That being said, if he was performing in training then he would be in and around the squad.

"Clearly, he hasn’t been doing it in training and that’s unacceptable. If that’s the case, I’m happy for him to go. I’m not sure he fits the new mould of inverted wing-back, the thing Ange likes to do.

"Maybe we could get a bit of money for him and then reinvest that."

The Verdict: Time to move on

There certainly appears to be some sort of issue with Bolingoli - if not, Postecoglou would have brought him back into regular training alongside his teammates, especially with the injury to Josip Juranovic.

It feels beneficial for all parties for him to be moved on at the end of the season, despite being hailed as a 'real asset' by SPFL pundit Alan Hutton, unless something drastic changes in the remaining weeks of the campaign.

Bolingoli's current Celtic deal expires in the summer of 2023, meaning the next transfer window would likely be their last opportunity to receive a decent fee for him, should Postecoglou indeed deem him surplus to requirements.
