Celtic's 2020/21 woes continue after they fell victim to St Mirren's sword this afternoon in the Scottish Premiership. The sixth place Saints put in an incredible performance to topple the reigning league champions and any chance of catching runaway leaders Rangers looks bleaker than ever.

The Hoops have two games in-hand, but their clash against St Mirren was also a chance to gain some momentum on their Glasgow rivals. But to Neil Lennon's dismay, they couldn't do enough to come away with a vital three points.

The Saints opened up the scoring after just 18 minutes through Kristian Dennis and despite an Odsonne Edouard equaliser, Celtic were dealt a blow just five minutes after the Frenchman's strike. Ilkay Durmus put the game to bed before half time and the Bhoys showed little promise of even getting back into the match.

It was a poor performance all round for Celtic, but one man who keeps sticking out as a below par player is loan signing Shane Duffy, whose glaring error it was that led to winning goal on Saturday.

Duffy stats vs St Mirren

The Brighton loanee has hardly painted himself in gold since he joined the Glaswegians. He has been that much of an unreliable option that Celtic are reportedly considering cutting his short-term deal short before the January transfer window closes.

Duffy's performance attracted criticism from Paul John Dykes on Twitter, who claimed that the centre-back was amongst Kristoffer Ajer, Nir Bitton and Scott Bain as Celtic's worst performers today. However, he added that he thought Duffy was the "worst culprit" for the Hoops' humiliating loss to St Mirren.

This isn't the first time the 29-year-old has disappointed in Scotland. According to Sofascore, averages less than on tackle per match, which is worryingly low compared to Ajer (1.5) and Christopher Jullien (1.2).

For a centre-back looking to find the next step in his career, this statistic isn't wowing anybody. With his links to Nottingham Forest potentially spelling an early end to his Celtic spell, Peter Lawwell should consider offloading the £6.3million-valued defender who is leeching him of £20,000 per week in wages.
