Barcelona forward Ousmane Dembele surprised many on social media this week.
Dembele, who is recovering from injury, was in England this week to take in a football game.
The Frenchman was seen at the Stadium of Light, where Sunderland took on Sheffield United in the Championship.
Sunderland owner Kyril Louis-Dreyfus appears to be a close friend of Dembele.
The two often exchange messages on social media, with Dembele congratulating the club when they were promoted to the Championship last season.
