Is Barcelona really strong this season? I would say a stable squad is needed to win the title. But we see in the Barcelona team, their forwards are very strong. But the midfield and defence are not that strong. Barcelona's midfield will be even weaker if de Jong leaves the team. Moreover, if the defence is not strong, Barcelona will not be able to perform well on a platform like the Champions League.
Looks like De Jong will stay with Barcelona next season. If he chooses to stay, the midfield will be stronger. barcelona have signed a defender in this summer window he is Andreas Christense, I think his presence will help the barcelona defense sector next season. barcelona have a stock of players for the position of defender. I don't think Barcelona will have a big problem in the lower or midfield because Xavi already knows which areas to improve this season before they are really ready to compete next season.
Yes De Jong will remain at Barcelona next season and Lewandoski has completed the move over.
Christense would improve next season because he will have enough time to play games.
Having brought in the player from AC Milan will help them in Midfield.
Serjio Busquet also have enough to offer not looking he is 34
