A Mike Williamson own goal handed Championship side Brighton a place in the FA Cup fifth round at the expense of Premier League Newcastle.

Will Buckley’s 76th-minute shot struck the defender and looped over the helpless Tim Krul.

It means Brighton have been rewarded with a lucrative trip to Liverpool, who dumped Manchester United out of the Cup, in the next round.

Newcastle wasted good chances, Leon Best twice firing just off target when well placed and having another shot saved by Peter Brezovan.

Yohann Cabaye had a shot charged down as Newcastle sought a late equaliser.

With Newcastle’s Senegal strikers Demba Ba and Papiss Demba Cisse due to make early returns from the Africa Cup of Nations, Best and Shola Ameobi were keen to make an impression up front.

Best almost made a perfect start when he found space on the edge of the box and his low drive flew narrowly wide.

He wasted an even better chance in the 12th minute when Ameobi picked out Best, who headed over from six yards.

The Seagulls rarely threatened, although lively winger Buckley gave Italian defender Davide Santon a difficult time.

The second half started in a similar vein with Ameobi rolling the ball to Best, whose his angled shot struck Brezovan’s legs. From the resulting corner, Ameobi’s 10-yard strike was deflected just wide.

Newcastle became increasingly frustrated and tempers began to fray with Cabaye kicking out in a challenge with Adam El-Abd and appearing to catch the Brighton defender in the face.

But six minutes later Krul was beaten. Buckley jinked into the penalty area with a clever step-over and hit a left-footed shot which was diverted past Krul by Williamson.

Dirk Kuyt’s late strike earned Liverpool a dramatic victory over Manchester United in the FA Cup fourth round at Anfield.

The tie seemed destined for a replay at Old Trafford as Ji-Sung Park’s powerful shot put United level after Daniel Agger had headed Liverpool into the lead – but there was a late twist to a surprisingly flat encounter.

Liverpool substitute Kuyt escaped the attentions of Patrice Evra with two minutes left to latch on to Andy Carroll’s flick and fire past United goalkeeper David de Gea in front of an ecstatic Kop.

It capped a perfect four days for Liverpool and manager Kenny Dalglish after reaching the Carling Cup final and their first Wembley appearance since 1996 at the expense of Manchester City on Wednesday, then sending their fierce rivals out of the FA Cup to reach the last 16.
