The Bavarian giants and the Catalan heavyweights will kick off their Champions League campaigns in a Group E encounter this week
Bayern Munich boss Julian Nagelsmann has warned that Barcelona still pose a major threat to his side's Champions League prospects, even without the departed Lionel Messi, ahead of the pair's clash on Tuesday.
The Bavarian giants and the Catalan heavyweights will kick off their European campaigns in a mouthwatering Group E encounter at Camp Nou this week, in arguably the pick of the first round of fixtures.
Ronald Koeman's side are entering continental competition for the first time without former captain Messi in over a decade-and-a-half - but regardless of the Argentine's absence, Nagelsmann feels they remain stern opposition.
