I highly doubt Bosz will have them defend deeply. It's not his style. If they counter attack, it'll probably be off recovering balls in midfield, unless it's off a corner kick or something. This Dortmund lineup is well suited to pressing and countering, but like Spurs are weak at breaking down a parked bus. Despite the apparent defensive strength of both teams so far this season, I foresee an up-and-down game, as I don't think either side will willingly cede possession to the other.
Based on Valverde's press conference I would expect Deulofeu to start with Dembele on the bench. SPORT speculating otherwise.
James already looking better than Muller has this season who Bayern should sell imo while they can still get premium return on him.
