Todd Cantwell and Chris Sutton have continued their ding-dong in a latest round of social media barbs.
The Rangers star - who is gearing up for the return to pre-season training with Michael Beale's men - responded to a Twitter poll by Football Scotland on the best pundits in the Scottish game and wrote: "I can tell you [it] isn't Chris Sutton."
The reply started a chain of responses on social media before the Celtic hero fired back at the Ibrox January recruit with some 'factial punditry' and referred to the midfielder as 'TikTok'.

Sutton wrote: "Here is some balanced factual punditry from last season TikTok you may not enjoy..you joined Rangers on a free from the Championship and lost every meaningful game against Celtic and won nothing.."
Cantwell himself didn't take too long to reply to the incoming Sky Sports pundit by writing: "Twitter troll has his notifications on then" alongside a crying face emoji and fishing rod.
It's not the first time the duo have clashed and with the season not even up and running they are at it again.
Both Rangers and Celtic will discover their Scottish Premiership schedules this week with the SPFL releasing the fixtures on Friday at 9am.
The Old Firm derby will be the one the supporters look out for first as the Hoops look to defend their domestic Treble under the leadership of Brendan Rodgers while Beale will be hoping his new-look side can end that dominance and bring back silverware to the Ibrox faithful.
