Barcelona spent too much in the past and that's why they have many financial issues in their teams which is the reason for them to sell some players. But recently they tried to spend less money and don't hire expensive players, that's why they could hire Messi for the next season. But I think they will try even harder to buy Bernardo Silva from Manchester City if they really want to make it happen.
The main reason why Leo Messi deal collapsed with Barcelona was simply because of the finances challenges they faxed, and Messi was certainly not ready to keep battling to make a way through a club that's experiencing such. Barcelona took a significant hit from FFP rules, violating them and being penalised, as well as facing restrictions on key important transfer market components. The bluagrana have really suffered the feat of their previous results, which has been hunting them in every transfer window. In terms of trends, the blaugrana have managed to relax several constraints while also regularizing the club's financial budget. After successfully luring IIkay Gundogan to Camp Nou this summer, Barcà president Joan Laporta announced his ambition to sign Bernando Silva from Manchester City.
Lionel Messi's return to Barcelona is a deal I never wanted materialize and I'm glad it didn't working, Barcelona would have taken step backwards if Lionel Messi had return to Barcelona because the team would have returned to Messi reliance yet again and it would have been a problem whenever he's retiring or quitting football generally.
And Barcelona-Messi didn't work out not because of FFP regulations, Lionel Messi was a free agent and so there wouldn't have been any signing fee, but his wages is not something Barcelona can afford according to La Liga rules, so it would have been impossible for Barcelona to register him in accordance to La Liga restrictions and rules.
