Last game was poor because Barcelona found no consistent path through the high press, and lacked consistency and threat when they did manage.
Busquets is the best ever at finding the space and angles in buildup, Pique (and Garcia) are great at that too. Pedri touched the ball 43 times, Griezmann played for half an hour longer and touched it 47 times despite getting extremely deep.
Some of the "brilliant minds" of this forum were very quick to blame Busquets last game, I am sooner to point the finger at someone like Pedri, who consistently has disappeared in games like these. If there is a path, Busquets will see it, but with these players it's very inconsistent. Their decisions are taken on the spot, and Koeman is very late to react, and seems to have little clue about what is happening.
With Frenkie, Pedri, Depay, Griezmann and Braithwaite, you have five players that are pretty good physically and technically, but who needs to be guided well, they all seem to play without instruction almost, and can't connect well.
Especially Dest, but also Alba to an extent, are too poor and inconsistent with the ball for being the main path in buildup. This is what happens when you push your DM between the CBs, the wing backs get more of the ball as the angles (and depth) to play through midfield disappear. Sometimes the dropping attackers get the ball, but they all do too little with it in Barcelona.
It is a shame that after Valverde left we didn't get to see Busquets, Messi, Puig, Alba, Pique, Garcia, and some of the other players, together again under a competent and confident coach that could use them well. Of course a slow player is terrible in a game of Hawaiian football, that's why you play to control the game. Instead a lot of people here still want to get rid of the few players that potentially are of World class. Well they will disappear in a few years, it's a shame they weren't used right for the last half a decade or more.
