Porto coach Sergio Conceicao blasted Arsenal counterpart Mikel Arteta after last night's Champions League penalty shootout defeat.

The pair clashed at the end of the game, with Conceicao wagging his finger at Arteta.

He later said: "The result was unjust. We deserved to go through.

“During the game and towards the bench he, in Spanish, I don't know if this is to do with Spanish managers, he insulted my family.

“And then at the end, I said attention, who he insults is not between us, he should focus on training his team because they have a lot of individual qualities to do that."

It's been suggested Arteta strongly denies Conceicao's claims.
