Tottenham were dumped out of the FA Cup in humiliating fashion as Harry Redknapp’s side capitulated to a 5-1 semi-final drubbing by Chelsea.

Didier Drogba opened the scoring just before half time before referee Martin Atkinson bewilderingly gave the Blues a second after the break despite the ball failing to cross the line.

Gareth Bale pulled one back for Spurs before Chelsea ran riot with goals from Frank Lampard, Ramires and Flourent Malouda to secure their place in the final against Liverpool on May 5.

Chelsea’s first goal came on 43 minutes when Drogba chested a long ball down with his back to goal before rolling Gallas and letting fly with a spectacular volley that rifled into the top left corner.

The west London side were 2-0 up in controversial circumstances in the 50th minute when referee Atkinson judged that Juan Mata’s shot crossed the packed Tottenham goal line.

Frank Lampard’s corner was punched high into the air by Carlo Cudicini and when Spurs struggled to clear, the ball fell to Mata who side footed into Assou-Ekotto and Cudicini on the Spurs line.

The referee did not hesitate in giving a goal, though replays showed the ball was blocked several inches in front of the line.

Tottenham were left seething by Atkinson’s decision and it did not take long before Bale pulled one back for Spurs on 56 minutes when he finished Emmanuel Adebayor’s run on goal.

The Togolese forward was played in behind the Chelsea defence with a perfectly weighted pass from Scott Parker and the striker was brought down by Petr Cech as he tried to round the goalkeeper but Bale was on hand to pass the ball into the empty net.

As the last man, Cech was perhaps lucky not to see red but the referee failed to produce even a yellow card for the foul.

Ramires made it 3-1 on 78 minutes when he was played in behind Benoit Assou-Ekotto by Mata and cooly dinked the ball over the on-rushing Cudicini.

Lampard sealed the win with a stunning free kick from 35-yards that sailed over the Tottenham wall and past the despairing dive of Cudicini after Drogba had been brought down by William Gallas.

Malouda’s injury time goal rubbed salt in the wound for his team’s fellow Champions League contenders as he slotted past Cudicini to send the Chelsea fans delirious. The scoreline was a reflection of Spurs’ capitulation during the second half as they chased the game.

Harry Redknapp will perhaps point to the referee’s decision to award Chelsea’s second goal as an influential factor but there is no doubt his side will need to improve defensively if they are to secure a top four place this season.

The game was open from start to finish and both sides created chances in a first half that, barring the Chelsea goal, Spurs edged in terms of chances.

Ledley King did well to block Drogba’s early effort from close range while Rafael Van der Vaart should have perhaps have done better when he fired over from 25 yards as Tottenham countered.

Scott Parker bundled his way into the Chelsea box soon after but was cut short by a stretching Frank Lampard who blocked the ball and allowed Ashley Cole to clear.

John Obi Mikel cleared a vicious in-swinging corner from Van der Vaart as Redknapp’s side pressed Chelsea but it was the Blues who went close to going ahead mid way through the first half.

Ramires nicked the ball off Kyle Walker and set off down the left. But when he crossed to Mata, who had sprinted half the length of the pitch, the Spaniard’s heavy touch meant the ball ran away into the hands of Carlo Cudicini.

Spurs thought they had scored at 0-0 when Aaron Lennon found Van der Vaart six yards out but the Dutchman’s header was blocked on the line by a retreating John Terry.

Tottenham again went close to opening the scoring when Van der Vaart’s in-swinging cross beat everyone and bounced into Cech’s right post.

Adebayor made a run across goal to meet the cross but made no contact with the ball and as the Blues goalkeeper stood motionless, it rattled the upright and bounced away from danger, somewhat summing up Spurs’ evening.
