Barcelona's performance in the last 3 seasons is very weak. Barcelona's performance has deteriorated since Koeman became Barcelona's coach. Although Xavi has been able to stabilize the team, he has not yet been able to form a completely strong team. Barcelona need more experienced players in defense. At the same time now Barcelona needs experienced striker. If Lewandowski joins Barcelona, I think Barcelona will be stronger. Next season, the title fight between Barcelona and Real Madrid will intensify.
Barcelona first of all need to solve their financial problems, at the moment they cannot afford to buy strong players, they are mainly hoping to sign free agents. Despite the fact that Real Madrid could not sign Mbappe, other strengthening of the squad will be made, and given the fact that Real Madrid is doing well with the budget, there is no need to think about any serious competition next season. Real will win La Liga again by a large margin.
