Chelseas decade of dominance over Spurs continued as a brace from Jimmy Floyd Hasselbaink and a Gianfranco Zola diving header gave the Blues their first back-to-back wins of the season.

Ailing Tottenham who have not beaten Chelsea since February 1990 - slid beneath a resurgent Blues side in the table as Hasselbaink put on another virtuoso display to bring his goal tally to six in two games.

This time George Grahams side who have now suffered four defeats in six games - had chances to end their wretched run. But they looked like a team reluctant to break the mould of recent history as they failed to cash in on Chelseas defensive lapses.

With the cutting edge of Sergei Rebrov up front Spurs might have found themselves two up in 10 minutes, but the Ukrainian striker was still sidelined with a thigh injury.

Only five minutes had gone when Dutch striker Willem Korsten latched on to Darren Andertons through ball to get in behind Mario Melchiot, but his powerful shot was straight at Ed de Goey and the giant Dutchman tipped over.

Within minutes, the slip-shod Blues back-line was once more found wanting, this time by Les Ferdinand, but his left-foot shot was turned round the post by de Goey.

The tide was then turned by Chelseas first cross into the box on 13 minutes. Swiss defender Ramon Vega, under pressure from the challenging Gustavo Poyet, clawed the ball from the air and referee Steve Dunne pointed to the penalty spot.

Hasselbaink, who cracked four goals against Coventry last Saturday, had no trouble tucking the ball home low to Sullivans right.

Ferdinand had a gilt-edged opportunity to equalise but, embarrassingly, was caught off-side two yards out by Korstens return ball and the game was as good as up.

Dennis Wises left wing cross was flicked on by Hasselbaink and Zola got in front of his marker to nod home his fourth league goal of the season.

Spurs stuttered into a second half rally as Korsten twice tested de Goey. But Melchiot hit the near post with a header following a cross from the by-line by Wise before Hasselbaink made the game safe with a low, curling strike that left Sullivan scrambling in vain.
