Erling Haaland was remarkably asked for his autograph in the tunnel by one of the assistant referees from Borussia Dortmund's 2-1 defeat by Manchester City.
The striker played 90 minutes at the Etihad as the Bundesliga side conceded a 90th minute winner from Phil Foden after Marco Reus had levelled six minutes earlier following Kevin De Bruyne's first half strike.
Haaland is one of the biggest stars in world football with a number of European clubs desperate to sign him and he was in demand at the Etihad as one of the linesmen cornered him for a signature.
