Manchester United have caused a headache for fierce rivals Liverpool in their preparations for next week's Champions League quarter-final second leg at Manchester City.
Man City travel to Anfield on Wednesday night for the first leg of their last eight clash – the ground where they suffered their only Premier League defeat of the campaign earlier this season.
Jurgen Klopp is confident his side can pull off another victory against the champions-elect, but the Reds boss has also revealed a hiccup in his plans ahead of the return leg at the Etihad Stadium.
