Ilkay Gundogan's decision to join Barcelona can be considered a wise decision because he still hopes to appear in Europe with a big team. Barcelona is a good team in the history of football, so joining Barcelona must be something good in a few seasons before approaching retirement.
Ilkay Gundogan can be expected to be able to provide a balance for Barcelona's midfield players next season. Barcelona no longer have senior players in midfield after Busquets stopped renewing his contract, so Ilkay's arrival at Barcelona is one to look forward as the best alternative for the balance of the game.
Gundogan is going to join Barcelona but still, but nothing is clear and there is still a chance for Gundogan to join another team even if he signs the contract with Barcelona. Because if Barcelona fails to register the contract of this player because of the financial issues he can join another team.
