Yep, Barcelona failed in UCL & Europa League. So, I believe Xavi will do something to build more Barcelona squad. One of the ways is to sign new players who can support the current players to be stronger. Barcelona seems to target winning UCL trophy next season. They must target a more prestigious trophy after they won La Liga trophy this season.
It is not grandiose to do but with conditions like that they must move quickly to vacate several players so that their cash is more stable, especially the demands of FFP are clear there that they must try to vacate around more than 170 million to be able to make their salary conditions safe and when in this case they want players who are certainly in the UCL then inevitably they have to vacate more than that because we must realize the vakue of the player will be much bigger for now especially in terms of salaries.
The risk now is only how Barcelona can get more fresh funds in order to patch up their current condition because if they only continue to add players without seeing their condition too it is the same as suicide.
