Ousmane Dembele has reportedly angered Barcelona boss Ronald Koeman by turning up late to training amid speculation linking him with a move to Manchester United.
The Red Devils are understood to have identified Dembele as a possible alternative to top target Jadon Sancho this summer with less than a week now remaining in the transfer window.
The France international suffered another injury-plagued campaign last season, being limited to only five La Liga appearances.
Dembele was forced to settle for a substitute role during Barcelona's season-opening 4-0 win over Villarreal on Sunday too, and AS reports that he arrived to training 15 minutes late the following day.
The 23-year-old has faced disciplinary issues for his timekeeping before, including turning up two hours late for one training session in 2018.
Barcelona are thought to be open to offers for the attacker, who was also linked with Liverpool before the champions signed Diogo Jota.
