I think it was right decision to drop him, was surprised it was from the squad completely.
Manga did ok at right back but is not an awful lot better than Peltier with the ball at his feet. Can only assume Warnock has concerns about Jazz Richards defensive abilities, otherwise he would be my choice at right back. Thought Warnock could have made a positive move by bringing Richards on after the red card, to give us a bit more ability going forward.
