My number one issue with this whole situation was that Chelsea clearly did not see Pulisic as a part of their future. Both management and the fanbase. I think it was unfair, but that's fine. You want to move in another direction because you don't think Pulisic is physical enough? Fine. Then transfer him away and MOVE ON. He was entering the prime of his career and you wasted 3 of these years.
Just hoarding talent all with similar skillsets, with no regard on how that's going to F up their lives, or F up the team chemistry is truly a disgusting way to operate a team.
