Porto boss Sergio Conceicao has said he was unimpressed with Manchester City coach Pep Guardiola's attitude during the Champions League encounter on Wednesday.

The two were involved in a heated exchange during City's 3-1 home win over Porto.

"The attitude of Mr. Guardiola during the game was not very pleasant and it wasn't of the [City] bench either," Conceicao said after the game.

"Besides the way in which he spoke to my players and the referees. He spoke about our country [Portugal] and they weren't nice words so I had to respond, because he who doesn't feel that [comments] is not the son a good person."

Conceicao also told the club's website: "I have to learn from him, in the way he conditions the referees, how he talks to the rival players and the [rival] bench. I have to learn a lot in that respect."
