Feels inevitable to me that they'll get Haaland at some point. I'm not actually sure he'll suit a Pep team, so perhaps in another year.
In the short term, they're going to spend an obscene amount of money this summer. Need to replace Fernandinho, Kompany, Aguero and at least 1 full back. Now that FFP is dead, won't be a problem for them, but still.
When they do that, they'll be a force again, because they are at least well-focussed on the type of players that suit Pep's system and if you have that kind of plan plus unlimited funds you will eventually succeed. De Bruyne, Sterling, B Silva, Mahrez and Foden is still a staggering amount of attacking talent that's not going anywhere.
