Tottenham Hotspur were knocked out of the FA Cup at the third round stage by bitter rivals Arsenal as they succumbed to a 2-0 defeat in a fiery derby at Emirates Stadium.

Arsenal took the lead through Santi Cazorla’s drilled shot on 32 minutes and, as Tottenham looked like forcing their way back into the game in the second half, the Gunners were gifted a second thanks to a defensive horror show from left back Danny Rose.

Arsene Wenger’s team had looked the better side in the first half, though Spurs remained a danger on the counter, but the Arsenal goal had looked under threat when Rose’s foul up as the last man back cost his team the game on 62 minutes.

The full-back was handed the ball in space on the half way line but dithered before trying to turn Rosicky who nicked the ball and ran the length of the pitch and dinked over Lloris.

It was a devastating blow to Spurs, and one that would have given Wenger a huge sigh of relief at a time when Tim Sherwood’s side looked like finding a leveller.

The visitors were denied a strong penalty shout when the ball bounced up into Cazorla’s outstretched arm with ten minutes to play but referee Mark Clattenburg dismissed the claims, leaving Tim Sherwood reeling on the touchline.

Tottenham will feel they missed a good opportunity to test Arsenal’s resolve, first by conceding the sloppy second goal and then to have missed out on what was a good penalty shout that would have set up a grandstand finish.

The tie of the round lived up to its billing in the opening stages, with both sides showing attacking intent and carving out chances at both ends.

Eriksen was denied by Fabianski when he found himself through on goal and Lloris got a hand on Walcott’s low shot from outside the box during a fast-paced opening.

Walcott again went close when his curled effort from 20 yards went inches wide after a slight deflection and Gnabry almost found the opener when his drilled shot from inside the box sailed narrowly over.

Arsenal were doing the pressing, with Spurs looking to counter, and it was Santi Cazorla who next went close with a beautifully curled shot that again missed the top corner by inches.

Walcott was played in with a superb one-touch ball from Cazorla but the forward showed a lack of composure and, with no-one around him, drilled the ball straight into the legs of Lloris.

Arsenal looked the more likely and it was the Gunners who took the lead on 32 minutes.

Gnabry cut inside infront of the Spurs back line and fed Cazorla coming in on the left who met the ball and drilled a rocket across Lloris and into the back of the net.

Arsenal’s tails were up and Bacary Sagna almost made it 2-0 at the stroke of half time when Cazorla’s whipped free-kick just evaded the full-back’s outstretched leg in front of goal.

Spurs came out of the blocks at the start of the second half and should have levelled through Adebayor but, after bringing the ball down well on the penalty spot, the forward skewed his shot on the turn when any good contact would have surely brought the equaliser.

With the chance gone, Arsenal were back to their attacking  best and Walcott hit the side netting from the tightest of angles after rounding Lloris.

Spurs continued to look dangerous, with Adebayor particularly lively, but Arsenal were handed a gift soon after the pressure began to build thanks to Danny Rose’s howler.

Spurs maintained their composure but were looking increasingly vulnerable as they pushed forward to grab a goal back, and Walcott almost made it 3-0 when he shot narrowly wide from the edge of the box with the visitor’s defence all over the place.

Arsenal then survived the Spurs penalty shout and defended the final ten minutes inside their own half before Ozil almost piled more misery on Tottenham at the death, forcing Lloris into a low fingertip save to prevent a 3-0 scoreline.
