Barcelona head coach Quique Setién admitted his side are suffering after their record 8-2 defeat in the Champions League quarter-final against Bayern Munich. The Catalan side were 4-1 down at half-time and went on to suffer their worst-ever defeat in Europe. But for Bayern and their manager Hansi Flick, the historic result was a demonstration of what the German side can produce as they head into the Champions League semi-finals against Manchester City or Lyon on Wednesday. 'Starting tomorrow, we'll have to gather our strength again for the semi-finals,' Flick said. 'That was our goal, to just make it to the semi-finals today, and we achieved that impressively, and that's why we're all very, very happy.'  Bayern Munich deliver Champions League demolition of dismal Barcelona
