Manchester United are watching Philippe Coutinho's situation at Barcelona closely.

Marca says World Cup winner Ousmane Dembele holds the key to Coutinho's long-term future at Barcelona and his recent performances could reduce Coutinho's longevity at the club.

The report suggests Barcelona hierarchy have been surprised by the recent showings of Dembele and the former Borussia Dortmund forward is in line to establish himself as a key figure at the club.

However, his success means Coutinho is less likely to feature in his favoured left wing role and may be forced to adopt a deeper role in order to feature regularly for the side.

According to the report this could persuade the former Liverpool man to consider his future at the club, with United still reportedly interested.
