We hear a lot about Messi in what he generates for Barca, time will tell, I get the feeling the figures are not true, he seems to have taken enormous sums out of the club, not saying he is not entitled to them but he himself and family have done very, very well out of Barcelona.
Barca were a huge club before Messi and they will be after, their debt is looking horrendous but it will be serviced.
The problem is one of direction, even under Laporta, they are making strange decisions, signing Aguero, Depay and probably resiginng Messi, yet still having Braithwaite and Greizman, how many strikers are they going to play each week?
I think they're good signings to be honest. Depay is quality, he's going to get 20+ goals a season and he's cheap. Braithewaite is one of their few sellable assets and Depay's a big upgrade. Also links very well with De Jong which is probably a sign he'll link well with Pedri and Messi too.
Koeman plays a 352/343 so I expect a minimum of 2 of Depay, Aguero, Messi, Trincao, Griezmann will play each game.
I actually think they could put together a La Liga challenging side without Messi. Front 3 of Griezmann, Depay, Aguero. Midfield of De Jong, Pedri and a new guy, and then a back 4 with Alba, Pique and a few signings.
