Kuyt goal sees off Man United

It was a sweet moment for Kenny Dalglish's side after its win over City in the Carling Cup semi-finals in midweek and against a background of heightened tensions between the two bitter rivals after Luis Suarez's eight-match ban for racially abusing United defender Patrice Evra.

Daniel Agger opened the scoring with a 21st-minute header for the host but Park Ji-sung equalised six minutes before the break and a replay looked on the cards until Kuyt grabbed the winner two minutes from time.

The match between Queens Park Rangers and Chelsea was also very much overshadowed by off-the-field issues in the build-up, with the teams meeting for the first time since John Terry was charged with racially abusing Anton Ferdinand during October's Premier League game between the two, a charge he denies.

The Football Association agreed the teams could forgo the traditional pre-match handshake in an effort to reduce tensions, which were ratcheted up the previous day when the Metropolitan Police announced they were investigating a 'malicious communication' sent to QPR and addressed to Ferdinand.

Events on the pitch did little to take the spotlight off Terry and Ferdinand, with Chelsea claiming a 1-0 victory courtesy of Juan Mata's 62nd-minute penalty for a debatable foul by Clint Hill on Daniel Sturridge.

The biggest shock of the day came in the final match as Brighton & Hove Albion dumped out Premier League Newcastle United with a 1-0 victory at the Amex Stadium.

It was a deja vu moment for Magpies defender Mike Williamson, who deflected in Will Buckley's close-range effort for the only goal 14 minutes from time.

Williamson also scored an own goal last season when Newcastle lost to then League Two side Stevenage in the third round of the competition.

In the 3pm (local time) kick-offs, once again it was Crawley Town which provided the shock of the day, the League Two side defeating Championship Hull City 1-0 thanks to Matt Tubbs' 57th-minute goal to reach the fifth round for the second successive year.

League One Sheffield Wednesday looked to have followed up its fourth-round win over West Ham United by knocking out another Championship side as Clinton Morrison lobbed it ahead at Blackpool but Kevin Phillips equalised in injury-time via a dubious penalty.

Last year's runner-up Stoke City made a great start, taking the lead in the fifth minute through Cameron Jerome, and Robert Huth added a second nine minutes from time for a 2-0 win at local rival Derby County.

Bolton Wanderers, the team Stoke beat 5-0 in the semi-finals in 2011, is also through thanks to Chris Eagles' 56th-minute winner against Swansea City - visiting goalkeeper Gerhard Tremmel culpable.

Luke Moore had put the Swans ahead but it was quickly cancelled out just before half-time by Darren Pratley, scoring for the first time since a goal for Swansea in last season's play-off semi-final.

A goal from Simeon Jackson five minutes from time earned Norwich City a 2-1 win at West Bromwich Albion in another all Premier League clash after Marc Antoine Fortune had cancelled out Grant Holt's first-half opener.

League Two Swindon Town was the hero of the third round after knocking out top-flight Wigan Athletic but it went down 2-0 to Leicester City as Jermaine Beckford made it five goals in the competition this season.

Birmingham City was a comfortable 4-0 winner against Sheffield United at Bramall Lane thanks to goals from 17-year-old Nathan Redmond, Wade Elliott and a brace from Adam Rooney.

Rickie Lambert's 31st-minute goal looked like it would be enough for Championship high-flyer Southampton to beat Millwall but Darius Henderson struck four minutes from time to secure a 1-1 draw.

In the all League One clash, Damion Stewart's own goal (12) put Stevenage into the fifth round for the first time in its history as it beat Notts County 1-0.
