​European giants, ​Barcelona have reportedly handed winger Ousmane Dembele a transfer ultimatum after the Frenchman turned up late for yet another training session. There have been concerns over the attitude of the 22-year-old off the field and this incident has now added to the growing unease in the relationship between the club and the player.

Dembele had angered the club management and staff by turning up late for a training session last November, and followed that up by repeating the same a month later. According to ​AS, the winger has once again managed to anger the club by failing to report on time for a training session, during the week leading up to their Copa del Rey final clash against Valencia in the last week of May.

As per the report, the winger used the hamstring injury he picked up against Celta Vigo to explain his absence and while manager Ernesto Valverde did not say much on the incident, his absence was not taken lightly by the club authorities who have given him a final warning.

The winger who joined the Catalan giants from Borussia Dortmund in 2017 has so far made 65 appearances for the club, scoring 18 goals and while he has impressed in spurts, Dembele has struggled with injuries which have kept him out of action for certain periods during the season.
