Manchester United have reiterated their stance on anti-owner flags after a supporter's banner was confiscated on Thursday night.
In footage that has gone viral on social media, a United fan is pictured getting his 'Glazer out' flag confiscated by stewards outside Real Sociedad's Reale Arena in San Sebastian, which prevented him from taking the flag into the stadium.
The fan wrote on Twitter: "United officials taking my flag off me going into the stadium because it has Glazers out on it."
