Thoughts on his tenure:
Don't know what to say about you Koeman. A period of 3-4 months of solid attacking Barca football. Other than that, too many ups and downs. The Blue ball season, as I call it, some very impressive matches and other decisions made me scratch my head. Why not utilize 5 subs earlier during matches knowing full well its a covid season with a lot of matches crammed in? Why rely on the same 2-3 subs every game? Why not adapt your tactics to the match? Why not play attacking football when you needed it the most (vs RM, vs PSG, vs ATM, etc.)? Were you afraid of their attacks? I mean you got dominated by PSG and RM when you played tentatively.
Overall it seemed like you had it figured out, but then you didn't. Why insist on starting Pique and Roberto when you had a good thing going on with Mingueza and Araujo? sure they made some dumb mistakes, but it doesnt help their confidence when you subbed them out as soon as the fuked up. Why didnt you do the same to Pique and Roberto?
Did the pressure get to you? The squad being pussies from Liverpool and Roma? Lots of questions to ask, but it's fair to say you are not the one to rebuild this squad or bring Barca back to greatness.
