LONDON, Nov 10: Premier League Southampton crashed 5-2 at second division Watford while Tottenham Hotspur gave new manager Martin Jol the perfect start with a 3-0 win at Burnley in League Cup fourth round action on Tuesday.

Arsenal's youngsters joined their north London rivals in the quarterfinals after a battling 3-1 win over Everton at Highbury while fellow Premier League side Portsmouth overcame second division Cardiff City 2-0 at Ninian Park.

Southampton's embarrassing collapse at Vicarage Road increases the pressure on under-fire manager Steve Wigley after just one victory in 12 league games this season.

Bruce Dyer put Watford ahead just before the break with a header but the visitor's troubles really began six minutes into the second half when James Chambers volleyed home from close range before adding his second just after the hour mark.

Heidar Helguson struck another volley four minutes later to make it 4-0 and although Southampton pulled a goal back through Dexter Blackstock their defence was undone again as Hameur Bouazza volleyed Watford's fifth goal six minutes from time.

Brett Ormerod's late strike to make it 5-2 was little comfort to Wigley who must now prepare his shell-shocked team for a local Premier League derby at home to Portsmouth on Saturday.

A double from Robbie Keane and another strike from Jermain Defoe gave Tottenham's new Dutch manager Jol the tonic he needed after a controversial week at the club following former France coach Jacques Santini's shock decision to quit on Friday.

Ireland striker Keane struck either side of halftime to see off Burnley, who beat Spurs in the same competition at Turf Moor two seasons ago, before his England counterpart Defoe curled a shot over Burnley goalkeeper Brian Jensen from 25 metres.

Midfielder Michael Carrick was impressive in his first start for Spurs as he set up the first goal and said he was now looking forward to facing Arsenal at the weekend.

"It was a good convincing win really and gave the lads a lot of confidence for Arsenal on Saturday," he said.

Arsenal put out a completely different team from the one that drew at Crystal Palace on Saturday and the first senior goals from Quincy Owusu-Abeyie and a double from Arturo Lupoli were enough to get past an experienced Everton side.

Thomas Gravesen put Everton ahead with a deflected 20-metre freekick after eight minutes but Dutch substitute Owusu-Abeyie equalised in the 25th minute and 17-year-old Italian Lupoli struck twice (52 and 85 minutes) to put Arsenal through.

Portsmouth striker Aiyegbeni Yakubu struck twice in the second half to see off a dogged Cardiff side as he hit the bar two minutes into the second half but followed up to score off the rebound before converting a penalty six minutes later.

Fourth round results:

Arsenal 3 Everton 1

Burnley 0 Tottenham 3

Cardiff 0 Portsmouth 2

Watford 5 Southampton 2-Agencies
