Celtic defender Colby Donovan's pre-match tunnel routine left Sky Sports pundits baffled before the side's 1-0 win over St Johnstone. The 20-year-old full-back was captured on camera repeatedly barging a wall with his shoulders in the McDiarmid Park tunnel ahead of the Wednesday evening kick-off.

The footage was picked up by studio analyst Kris Boyd, who expressed his confusion live on air. "I'm not quite sure what Colby Donovan was doing," said the former Kilmarnock striker. "He's barging into that wall there."
