Sunderland boss Ricky Sbragia launched aÂ stingingÂ attack on his opposite number Phil Brown after watching his side edge a tense Barclays Premier League relegation battle at the Stadium of Light.
Sbragia was incensed by comments Hull bossÂ Brown was alleged to have made in the build-up to the game in which he expressed his surprise at the Black Cats' struggle after the money they spent on new players in the summer.
Sbragia said: "Motivation-wise it wasn't a problem because we just put the stuff on the walls what Phil Brown said about Sunderland Football Club."
He added: "I think a manager should just talk about his own club rather than criticising other clubs and what they've paid for players.
"I didn't have to chat with them, I just told them there was some good reading for them in the dressing room.
"I think the players have been excellent. I don't think they've under-achieved. It doesn't matter if they cost Â£10million or Â£1million - they go out there and give their all."
Brown expressed his surprise at Sbragia's criticism and was unrepentant over his comments, which he believes were exaggerated by headlines.
Brown said: "Is somebody questioning that they haven't spent the money? Is he saying that was an inspired performance? It's Ricky's prerogative, it's nothing to do with me."
