BBC Sport Scotland pundit Tam McManus has taken to Twitter to troll Celtic star James Forrest for looking as though he is wearing boys’ shorts in the 1-0 Europa League win against Zenit St Petersburg on Thursday night.

The 26-year-old was in sensational form against the Russian side at Parkhead, but the BBC journalist seemed distracted by the Partick Thistle match-winner for Celtic tight shorts rather than his performances.

The former Hibernian player turned pundit suggested Forrest had been working on his leg muscles in the gym on his personal Twitter handle during the game.

“Has James Forrest been squatting 200kg or has he got small boys’ shorts on,” he said.

James Forrest has arguable been Celtic’s best player this season and on Thursday night he proved that once more as he played a crucial role in brilliant performance that earned Celtic a win.

He has notched 46 appearances across all compeition for Celtic this season, netting a stunnig 16 goals in the process and supplying three assists.

While the likes of Scott Sinclair and Moussa Dembele have not been as impressive as Forrest this season, the Scotland international has been able to force himself into the best at Celtic this season with brilliant performance after brilliant performance.

Up next for Celtic is a clash against St Johnstone in the Scottish Premiership before they travel to Russia to play Zenit in the second leg.
