Premier League's Watford were made to sweat to beat lowly Championship club Queens Park Rangers 1-0 on Friday and book their spot in the FA Cup quarter-finals for the second time in four seasons.
Watford had possession in the first half but struggled to make any inroads against the solid home defence until Etienne Capoue swept a low shot into the net in first-half stoppage time.
The visitors did it well in the final minutes, dropping deep to protect their lead as QPR frantically searched for an equaliser and with captain Toni Leistner missing a golden opportunity from point-blank range.
Premier League heavyweights Manchester City are in action on Saturday at Newport County.
