Other than the back line, I'm not sure there is much I would want to change at Barcelona even if there were capacity for it and upfront, the addition of Memphis Depay is a great deal imo, the other players I would have the team to make a move for are either off reach or just too expensive so it's still great progress in the transfer zone so far this year, than the multi millions spent of the likes of Greizmann and Coutinho at some point.
Right now, nothing of good can be made of or come of these players. I feel for them, really but, its football and the way it is. For Griezmann to be specific, his salary is a lot too high and with the financial crises in Barcelona, I'll understand why his so targeted for a possible transfer but then, all these is been done because, the club can not afford to loose one man.
I wonder what would become of Barca when they actually do because, they will one day.
When it comes to Griezmann, there have been some rumours about him like Manchester City are interested in him closely and they want to sign him this summer. As Barcelona have signed Depay, I think that they may give green light to a transfer like this. And they would make a really profit thanks to him. They need to make their finance much better to be able to take a deep breath.
