It's not only Xavi, even Lewandowski, is a player who is quite happiest with Barcelona this season. Because he has only had one season with Barcelona, he immediately becomes one of the stickers who is quite aggressive in scoring goals. In making purchases for players, I think Barcelona will exercise the option of selling players first, where many Barcelona players are reported to be released in the transfer window. I think Xavi and Laporta will be able to make significant changes for Barcelona in the transfer window. They have a lot of good quality players and just need to balance their strength by bringing in 2 or 3 players. Additionally they can take the option to sell some players to match their spending.
Barcelona are certainly one of the strongest clubs in Laliga, capable of signing any player on their radar, but their finances are uneven and they have unresolved difficulties with the FFP organization. Both Xavi Hernandez and Juan Laporta are working on a good project to help the club return to its former glory. They will plan critical signings that will benefit the club, and one thing I admire about the blaugrana is that they have good judgment in bringing in promising players. The club will most likely dispose some of their players in order to acquire finances to sign new players during the transfer season.
