Manchester United full-back Patrice Evra exploded with anger at Nemanja Vidic in a training ground bust-up, according to The Daily Mail.
If reports are to be believed, former Red Devils boss David Moyes had to restrain the duo after Vidic accused the Frenchman of neglecting his defensive duties in the side's embarrassing 3-0 home defeat to Liverpool in March.
Vidic was shown a red card as Manchester United were heavily beaten by their rivals from Merseyside.
And now it appears that the duo - post the Liverpool clash - collided on the training pitch at Carrington.
Reports have suggested that, as well as Moyes, other members of staff intervened as the duo collided on the training pitch.
The duo joined Manchester United in the same transfer window in January 2006, and have since made up, with Vidic set to depart Old Trafford for Inter Milan this summer.
Manchester United fans will be hoping, however, that Evra is in a red shirt at the start of next season, despite the Frenchman being out of contract at the club next month.
