The long-running spat between Rafael Benitez and Sam Allardyce showed no signs of ending after Liverpool's 2-1 victory over Blackburn at Anfield.
Neither have been complimentary about each other in recent years, stemming back to the Spaniard's first match against Bolton in August 2004 when Sami Hyypia sustained a broken nose in the opening minutes.
Prior to this match Allardyce claimed his opposite number had turned Liverpool into a side scrapping for results, akin to his former Wanderers team.
Benitez responded after the game by ironically suggesting Barcelona - regarded as the best footballing side in the world - were considering copying Blackburn's style.
"We try to do our talking on the pitch. If they are pleased with the way they play under this manager it is their decision," Benitez said. "They have a style and they are a team that plays this way under this manager.
"We won so we they have to be thinking about whether the style is good or not. I think it is a model for all the managers around the world, their style of football, his behaviour. It is the perfect model for all the kids and I'm sure all parents will enjoy this model and encourage their kids to be the same. The style of football, I think, Barcelona are thinking of copying."
