Eamon Dunphy tore into Pep Guardiola and Man City after they were soundly beaten 4-0 by Barcelona at the Nou Camp tonight.
The English side were trailing to a Lionel Messi goal when their goalkeeper Claudio Bravo handled the ball outside the box and was sent off. Barcelona promptly tacked on three more goals to equal Guardiola's heaviest defeat as a manager.
Many were stunned by the Spaniard's team selection, with Sergio Aguero left on the bench for the second straight game.
Afterwards on RTE, Dunphy was highly critical of both the Man City manager and the players after Luis Enrique's men ran out comfortable winners in their Champions League clash.
"They were a shapeless shambles," Dunphy said.
"They were terrible. The decision to leave Aguero out of the team was mystifying. Barcelona weren't anything like they can be but they took advantage of the shambles.
"The story of the night is the humiliation of Pep. The way his team performed, Stones, Sterling - I didn't see Sterling all night, Kolarov, Otamendi, he can't run.
"Nolito? He is uselss.
"Darragh (Maloney) asked me if his players let him down, I would ask a different question - did he let his players down?"
Dunphy and his colleague Liam Brady both left tonight's game questioning whether Guardiola's lofty reputation in the game - built on winning six league titles in sevens seasons as a manager - is justified.
"I think there is a cult around Pep Guardiola, I have said it before," Dunphy said.
"I thought the Premier League would test him and I think he has a lot to prove. I think what he is trying to prove is that he has found a new way of playing."
"There is a huge question mark of whether this guy is the guru that everyone says he is," Brady added.
