Bayern Munich defender Jerome Boateng says he could see problems between Lionel Messi and Barcelona even before their stunning Champions League quarter-final victory.
Barca suffered one of the worst defeats in their entire history at the hands of Bayern in Europe last season. Hansi Flick's men knocked them out of the Champions League at the last eight stage, winning 8-2 in a one-off knockout tie in Lisbon.
The humiliating result cost Quique Setien his job, and compounded a miserable campaign for Barca which saw them fail to win a trophy for the first time since 2007-08.
