Watched this game. Barca played well in spells, but good work gets undone by that very high line. It isn't working like it did at this point last season. Girona got in so often and their finishing was awful (commentator said they were near bottom of the league for shot conversion). The thing is, they don't even have to work or do anything special to get a race against the goalkeeper - it's just one man holding his position, waiting, then a ball in behind and he's away. Faster attackers llke Mbappe won't be caught and will have a clean shot.
Lovely goals by Pedri and Witsel, though. The goal to win it was nice, but you cannot rely on late winners after the opposition miss sitters every week.
The warning signs are there and surely Flick cannot continue to ignore them? Barca are capable of playing beautiful football sometimes, but it's undone by mistakes and that high line. It didn't cost them at the weekend but it might in future.
