1550: HALF-TIME VERDICT by BBC Sport's Chris Bevan at the stadium:
It's been a frantic opening 45 minutes at the Millennium Stadium but it is
Watford who hold the advantage at the break.
Leeds, with only Rob Hulse up front and their widemen seeing little of the
ball, seem short of ideas going forward.
Watford are not seeing much more of the ball but their attacking players
have pace in abundance and that has been the main difference between the sides.
Every chance so far for both teams has come from set-pieces and the second half looks like being a keenly-fought contest with Leeds trying to find an equaliser while being wary of Watford's speed going forward on the break.
1547: Leeds have a free-kick from a dangerous central position but Eddie Lewis sends his effort from 35 yards just high.
1544: Sean Gregan rises highest at the far post but heads a diagonal Leeds free-kick the wrong side of the post.
1542: Leeds boss Kevin Blackwell and Watford counterpart Aidy Boothroyd, who were working together just over a year ago, exchange words on the touchline after the latest Hornets chance.
1535: Blackwell's tactics of lumping the ball to lone striker Rob Hulse are not paying off and some Leeds fans are already showing their frustration.
1530: The Watford players celebrated their goal in a huddle apart from Jordan Stewart who went over to speak to manager Boothroyd.
Boothroyd had been standing in his technical area for the first 25 minutes - only now has he sat down.
Leeds fans had been the noisier during the opening exchanges but Watford supporters still waving flags and banners following their goal.
Noticeably the Leeds half of the ground is a complete sell-out but there are
masses of empty seats in the Watford end.
