Celtic defender Liam Scales insists there is no crisis of confidence at the club after Martin O'Neill's side suffered damaging back-to-back defeats. Thursday night's 3-1 Europa League opening loss to Ferencvaros followed the 3-0 Premier Sports Cup exit to Rangers, who visit Celtic Park in the Premiership on Sunday. "Definitely not, no crisis," Scales replied when asked if confidence levels were significantly dented.
