Yes that's right, and the impact of the injury was very disruptive to his performance on the field so that Fati could not fully display his best performance as usual. his career seemed to stagnate there especially followed by many competitors for him at Barcelona. I think this is indeed the best decision for him and Xavi also said this decision was none other than so that he could play full minutes without intense competition at Brighton and it was also for the good of Fati. Obviously I also don't think Fati would turn down an offer to play in the Premier League, and one of the reasons for his departure is because he really believes in De Zerbi.
