Manchester City hero Craig Bellamy was furious with former Manchester United midfielder Nicky Butt during Vincent Kompany's testimonial.
Bellamy was hacked down by Butt late in the first half - and the former City star was furious.
The Welshman shouted at United hero Butt over his rash tackle.
Butt waved Bellamy away but their heated argument continued for a few minutes after the challenge.
Bellamy has followed Kompany to Anderlecht to take charge of their U21 team.
