Celtic boss Neil Lennon didn't appear to take too kindly to Mikey Johnston hobbling off against St Johnstone - appearing to tell the winger to "f*** off" out of frustration.

BT Sport cameras caught the manager mouthing the words to his player after Johnston was forced to come off the pitch following a late challenge. It looked like Johnston refused to be substituted moments earlier when Patryk Klimala eventually replaced Odsonne Edouard before he pulled up again and walked away to leave the Hoops with 10 men.

As he trudged towards the early bath, Lennon was visibly angry with the player and seemingly let him know it in no uncertain terms.

Celts managed a 3-0 win, in the end, thanks to goals from Olivier Ntcham, James Forrest and Leigh Griffiths.
