Manchester City boss Pep Guardiola admits he may have gone over the top in his row with Sergio Conceicao during their Champions League defeat of Porto.

The Porto coach accused Guardiola of saying "unpleasant things", including about Portugal.

Guardiola said on Friday: "Well, we didn't want that, to be unpleasant.

"Sérgio Conceição believes so. Maybe he's right. I don't think that's the case. Honestly, I don't think so.

"I am satisfied with the way we behaved from minute zero to minute 90, but if he believes that that was the case, fine, maybe he's right. We'll see."
