Manchester United legend Roy Keane and former Manchester City midfielder Alfie Haaland refused to meet ahead of the derby on Sunday afternoon.
There is a belief that Keane ended Haaland's footballing career after a horrible tackle back in 2001.
According to Samuel Luckhurst, Keane and Haaland were 25 yards apart at the Etihad Stadium but refused to reunite when a broadcaster asked.
The pair spent a season together at Nottingham Forest before Keane left for United in a deal worth £3.75million, the British record fee at that time.
