Ya it was because of Champions League and Europa etc. New formats = more games. So now those without UEFA football play. It's gonna get worse when teams qualify for more rounds and cups. We even had 1 game from 2nd match day already delayed IIRC.
Olmo was one of the most important key transfers that Barcelona could ever make. I like to watch him playing as you never actually know what his next move will be, you only know that it is going to be genius. He is an awesome defender and he is an awesome striker at the same time. A true allrounder with all the qualities a coach can wish for. No need to talk about Yamal, he is going to be one of the best in the world and if he can retain this level of efficiency, damn how valuable is he going to be for Barcelona?
The thing about Barca (usually or traditionally), every piece of the puzzle is as important to the team as one another. Messi for a long time was central, but he had a huge axis around him, and all of those were important. For us now, I think Lewandoswki is the weird one out, important but not quite part of the structure IMO.
Olmo for sure helps us build a nicer puzzle but we really need our Pedris, Gavis, de Jongs, and hopefully now Olmo to be the new axis which we never replaced once we lost of Busquets, Iniesta, Xavi.
Agreed no need to mention Yamal. Just see for yourself, self explanatory.
