Barcelona seriously needs Alvarez to come as a new striker. I believe he can suit Barcelona's gameplay well, but only wonder on how much he priced by Atletico. Logically, They have no good financial to buy him out from Atletico. However, they can do something to raise the fund like selling lots of their young lads.
It will be interesting to see Alvarez to play at Barcelona. He had been coached by Pep, which has also Barcelona DNA.
For Alvarez's current price it might increase and it is certain that Atletico Madrid will not let go of the player if he does not fit their wishes. Barcelona is currently experiencing financial problems and deciding to buy Alvarez is not the right choice even though they can sell some young players to raise money. The squad depth that Barcelona currently has is quite good and they have quite productive attackers who can be utilized for the next season and it would be better if the existing players could be utilized so that the club's finances can be better next season.
