Never one to mince his words, ex-Chelsea and Celtic striker Chris Sutton has made his fair share of headlines this weekend for some outbursts on live TV.On Friday, for example, Sutton slammed former teammate Craig Bellamy for his comments about Celtic manager Brendan Rodgers.According to Bellamy, Rodgers would struggle to find a job in English football because no one cares about his achievements in Scotland.Sutton responded furiously, saying: "It's another cheap shot at Scottish football. It was ignorant, it was ill-informed."How Craig Bellamy is in the minds of what boards down south think when they're choosing a manager, I couldn't tell you. It's absolute garbage."And on Saturday, following Celtic's 2-0 win over Rangers at Ibrox Stadium, Sutton tore into striker Leigh Griffiths for his behaviour.In two separate incidents, Griffiths not only picked his nose and wiped snot on a Rangers corner flag, but tried to tie a Celtic scarf round a goalpost during the full-time celebrations.Stewards had to escort the 27-year-old off the field of play, with Sutton saying afterwards: "Leigh Griffiths, the great player that he is, I'm a huge fan of his but he has to stop these silly antics."Tying a scarf round a post. He got banned from Rosenborg because of his stupid antics. It's not befitting of a Celtic player to act that way. Leigh Griffiths needs to grow up."Sutton had a case on both occasions and now he's the talk of the town once again for what happened at the beginning of Scottish Football Extra on Sunday.In the video below, Sutton gets completely wiped out by a sliding tackle from fellow BT Sport pundit Stephen Craigan on live TV.

SUTTON FLATTENED ON BT SPORT

Solid tackle. Sutton isn't the most popular of pundits amongst football fans, who all revelled in seeing him humiliated. Even Stoke City midfielder Charlie Adam found it hilarious.

Better watch your back, Stephen.
