Kenny Miller has recalled the time Barry Ferguson and former Rangers teammate Sergio Porrini came to blows during a training exercise under Dick Advocaat.

The ex-Gers striker, who retired last week, described the bust-up between a fiery Ferguson and his Italian counterpart.

Speaking to Si Ferry on his Open Goal podcast, 40-year-old Miller remembered Ferguson as being "mental" and not taking things well when Porrini refused to do his bit after a slightly wayward pass during a drill.

Laughing, Miller said: "Early doors you see what [Ferguson] is like and you just have to get on with it. He was mental, Fergie. We used to train at Stepps. We would report to Ibrox before going to Murray Park.

"We were doing boxes. Some guys would just think 'It's just Fergie we will just leave him' but other guys maybe had a wee bit about them. "We had Porrini, Italian, character, he had a brilliant career and played with some massive players and he's maybe thinking 'this wee Scottish guy who is 22 isn't telling me what to do'.

"So we are in boxes, so Fergie again whether he misplaces, gives it away, it's not his fault. So he played a pass literally a yard to the side of Sergio. I don't know who was at fault to this day but Sergio was like 'I'm not going in' and Fergie is like 'I'm not f***ing going in'.

"They end up coming to blows about who is going into the box."

The bizarre confrontation didn't quite end there, though. When then-manager Advocaat demanded kit man Jimmy Bell drive the pair back to Ibrox, Ferguson attempted to play down the issue. But when the Dutchman refused to accept it was over and done with, the former Rangers captain snapped back, Miller says.

"So wee Dick said: 'Jimmy, go drive them back up to Ibrox please. I'm not having that away back up to Ibrox. Fergie, being Fergie had his arm around Sergio saying 'Naw, naw look we are fine. We're back. We're fine'

"But Dick said, 'Back to Ibrox'. Fergie volleys the ball away and says 'your training is s**** anyway' and goes straight up the road."
