Hansi Flick said Barcelona need a break after Atlético Madrid inflicted a third straight home league defeat on them to replace them at the top of LaLiga on Saturday.
Alexander Sørloth scored a 96th-minute winner at the Olympic Stadium to seal a 2-1 win for the visitors after Rodrigo De Paul had cancelled out Pedri's opener as Atlético came from behind to make it 12 consecutive wins in all competitions.
Atlético's form could not contrast more with Barça's, who have now won just one of their last seven league games heading into the winter break in Spain.
