Visit of Bratislava is must-win opener, says Lambert

Former skipper Paul Lambert says victory at home to Slovan Bratislava is a must if Celtic are to progress to the Champions League knockout rounds for the first time since season 2012-13. Celtic begin their campaign in the tournament's new format on Wednesday night against the Slovakian champions. "I don't think people should think it's going to be an easy game," Lambert told the BBC's Good Morning Scotland radio programme.
