Apparently before he left Aston Villa there were a slew of incidents due to his negative demeanor which basically hastened his departure there.
From the Athletic: "Duran has, occasionally, been a disruptive presence. There were instances of him turning up late and disturbing team meetings. His attitude had been noted by multiple sources, who felt he could stray dangerously close to breaching Villa’s disciplinary standards, which were set by leaders in the dressing room."
So I'd imagine with him making all these abrupt moves in a short amount of time ,his disruptive tendencies have just become more prevalent since he was at Villa , it would probably be best to swerve.
