NOTTINGHAM — FA Cup holder Arsenal was dumped out of the FA Cup by Nottingham Forest Sunday, losing a dramatic tie 4-2 in the biggest shock of the third round.

Eric Lichaj scored twice for the home team in the first half either side of a Per Mertesacker goal before Ben Brereton converted from the penalty spot to give Forest a 3-1 lead after the break.

Danny Welbeck gave the 13-time winner hope with just over 10 minutes to go but Kieran Dowell netted from the penalty spot again to seal a 4-2 win for the second-tier side over the Premier League visitors.

It is the first time Arsenal has lost in the third round since 1996 and the first time since Arsene Wenger took over.

Earlier, lowly Newport County came from behind to send Championship side Leeds United crashing out but Premier League West Ham stayed alive with a goalless draw at Shrewsbury.

Elsewhere, Tottenham scored three goals in just eight second-half minutes to see off the challenge of League One side AFC Wimbledon.

In the early kick-off, on-loan forward Shawn McCoulsky headed in a dramatic 89th-minute winner for Welsh club Newport to seal a 2-1 victory against 1972 Cup winner Leeds and send the crowd at Rodney Parade wild.

Leeds had taken an early lead in the third-round tie when Gaetano Berardi's deflected long-range shot found the net.

But Newport, currently 11th in League Two — the fourth tier of the English game — leveled 14 minutes from time when Leeds defender Conor Shaughnessy sliced into his own net.

Infused with fresh belief in front of a passionate Welsh crowd, Newport pressed for a winner, and with a minute to go on-loan substitute McCoulsky rose highest at a corner to head in the decisive goal and send the stadium into raptures.

Leeds was then reduced to 10 men when substitute Samuel Saiz was immediately sent off over an off-the-ball incident.

The Championship visitors had made nine changes from the side held by Nottingham Forest on New Year's Day, and manager Thomas Christiansen's decision backfired in a frenzied finale.

It is another miserable result in the FA Cup for Leeds, which crashed out in the fourth round last year to non-league Sutton United.

West Ham had goalkeeper Joe Hart to thank for keeping them in the Cup with a 0-0 draw after an uninspired performance against Shrewsbury Town of the third tier.

The England goalkeeper, returning to the club where he started his career, was handed a cap from the crowd as he battled against the slanting winter sun.

He made a fine save from Mat Sadler with about 10 minutes to go until the interval and repeated the trick against Alex Rodman to keep the score at 0-0.

The League One high-fliers continued to take the game to David Moyes's team in the second half but there were few clear-cut opportunities for either side.

Shrewsbury's Jon Nolan had a golden chance to seal a dramatic victory in the dying minutes of normal time but blazed over and the two sides will meet again at the London Stadium.

At Wembley, Harry Kane broke the deadlock against AFC Wimbledon with just under half an hour to go before Kane again and Jan Vertonghen made it 3-0 to put the game beyond the reach of the visitors.

On Saturday, League Two Coventry City sent Premier League side Stoke City crashing out, prompting the sacking of Mark Hughes. — AFP
