#3)Financial issues
While Griezmann is most likely to join Barcelona at the moment, he is being tracked by other clubs like PSG which could raise his asking price. Moreover, his arrival would mean that he would demand high wages from the club which could hamper Barcelona's finances significantly.
While, Gabriel Jesus earns £90,000 per week at Manchester City, Griezmann earns £335,000 per week at Atletico Madrid which is significantly higher than the Brazilian's.
With so many players with high salaries at Barcelona, the board could find it difficult to manage the high wage bill.
Moreover, the addition to Frenkie De Jong and possibly De Ligt to the squad could complicate things further, if Griezmann were to arrive as well.
Bottom Line
While Griezmann is certainly a high quality player, he might find it difficult to adjust to Barcelona straightaway. However, the arrival of Jesus could be less complicated as he has age on his side and has the right amount of quality and time to adjust to the Barcelona style of play.
