I expect huge flak for this but I hope they beat Barca and qualify for the semi for two reasons.
Firstly if they have a CL SF to look forward to they won’t regard the derby as the most important game left for them. Pogba turns it on when he feels like and if the derby was their biggest game left he’d be well up for it but with s potential SF against the dippers on the horizon he may well keep his powder dry. Ole may even rest players.
Secondly a brutal rough house semi against the rags would take more out of the dippers mentally and physically than a tie against Barca would imo and any little edge we can get in the title run in I’ll take even if it means a glory night for the rags.
I’ll get my tin hat on.
