Erling Haaland was remarkably asked for his autograph in the tunnel by assistant referee Octavian Sovre following 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 canceled out Kevin De Bruyne's first-half strike.
Haaland is one of the biggest stars in world football. Some European clubs were desperate to sign him, and he was in demand at the Etihad as the Romanian official cornered him for a signature.
