New Chelsea signing Thiago Silva’s agent has blasted former Arsenal manager Unai Emery.

The two spent time together at PSG but Paulo Tonietto has laid into the former Gunners boss.

He told L’Equipe: “PSG lost two years the day they appointed him.

“His problem is that he has trouble managing the stars. When he went to Arsenal, the first player he got angry with was Mesut Ozil.

“He’s a good coach to play in the Europa League, not the Champions League. The suit was too big for him. He was a terrible coach for PSG.

“If there had been a coach of another calibre during these two years, PSG would have already won the Champions League.”
