At least it was enough to fill some of the remaining vacant positions before, such as Christensen who will add to the list of Barcelona defenders, Kessie as a new midfielder, and strikers such as Raphinha, and Lewandowski. Barcelona are fully prepared, I don't think Xavi will add any more while on the other hand they don't see to have any desire to let go of their players. Even De Jong, who was previously reported interested in Manchester United, has not received approval from Barcelona.
The composition of the players in Barcelona seems to be sufficient, moreover there are additional purchases in the transfer market this time, but what needs to be noted, Barcelona do not have players as ready as they used to be like in the era of Leonel Messi, Xavi has a tough job next season, so they can compete with Real Madrid and other top clubs
Barcelona looks really ready for the season quite alright, they've strengthened the squad to significant level with those transfer made, but I'd have loved to see a few more centre backs, Lengelet left the club on load already and Pique can't be counted on imo, that leaves us with players like Ronald Araújo (the best of them imo), Andreas Christensen(still new, but should be highly effective), Eric García(Lacking experience and confidence) Óscar Mingueza (not reliable as a CB), Samuel Umtiti (Injury prone), and the team have also only got one recognized LB and RB, so I definitely would be love the team to get rid a few of the surplus frontline and reinforce the backline as well.
They don't have enough experienced players in various positions, less flying hours will affect their performance this season, the experienced players they have are already in the old category, so it's difficult to mix with easy players, this heavy burden is quite difficult for Xavi to handle. find a squad that is ready and able to compete, but to be in the top 3 of the table, Barcelona are still able to catch up this season and I don't think it will be difficult
I think Barcelona are trying so hard to fix the problems but the means they're going about it would only fix the problem temporarily, I know they the chances that Barcelona would compete pretty well at every football level this coming season would be very high, but where do you see Barcelona in 3-4 years with their current squad ? They'll most likely would have lost Busquets, Lewandowski, Aubameyang, Pjanic, Braithwaite, Neto, Sergi Roberto, Jordi Alba, Gerard Pique and probably Depay who is currently (Age 28), that's a total of 10 players and only 4 of those players have just been with the club for more than 2 years ago, what then was the reason for selling Luis Suarez, just to get some other oldies, I thought the initially plan was to rebuild the team with youngsters, but what's the chances of Ferran Torres playing upfront well ahead of Lewandowski that the club likely would have in 3-4 years time, wouldn't it be the same with losing Arthur for Pjanic who's been literally surplus to requirements ever since, but will be back on the payroll this season if the club can't find another club to have him out on another unpaid loan ?
