Manchester United's forgotten Dutchman Donny van de Beek could be their secret weapon to inflict more misery upon Jurgen Klopp.
Van de Beek, 23, has started only two Premier League games for United since his highly-publicised move from Ajax but played the full 90 minutes against Watford in the FA Cup and is set to face Liverpool in Sunday's fourth round.
'I wouldn't say that Donny is happy, of course he wants to play more, but he is driven and goes about his job in the right manner,' said Solskjaer.
