Rio Ferdinand has highlighted one specific worry he has for Man United in the Europa League final against Tottenham.
United will take on Spurs in Bilbao on Wednesday night in the showpiece event as Ruben Amorim's side aim to rescue what has been a dismal season.
Things haven't been much better for Tottenham, with the North London club one place below United in 17th in the Premier League after 21 defeats in 37 games.
The winner of the clash will secure a spot in next season's Champions League, meaning it could prove to be a real sliding doors moment for both clubs.
