An amazing game at St James' Park saw Newcastle produce a stunning comeback from 4-0 down to earn a draw that shocked title hopefuls Arsenal.
The Gunners were three goals ahead inside the first ten minutes - Theo Walcott scored after 44 seconds before a Johan Djourou header and a strike from Robin van Persie.
Van Persie headed the visitor's fourth but Abou Diaby saw red after the break for pushing Joey Barton and Kevin Nolan and then it all went wrong for the team from North London.
Joey Barton scored penalties either side of a strike from Leon Best before Cheik Tiote's long-range equaliser.

The second period was more low key with City content to sit on their lead and record the three points together with a clean sheet.
Stoke battled back from twice falling behind to record a 3-2 win over Sunderland at the Britannia Stadium courtesy of two goals in the last seven minutes.

John Carew then levelled just after the half-hour from what seemed an offside position.
The Black Cats leading scorer Asamoah Gyan, with his eighth goal of the campaign, fired in just after the break and that's the way it remained with seven minutes to go.
Two Jermaine Pennant free-kicks were to prove the saviour for Stoke as on both occasions, the second deep into added time, defender Huth was on hand to score and totally deflate the Sunderland team.
Louis Saha scored all four of the Toffees goals in an entertaining encounter at Goodison Park.
Saha stroked them ahead but Alex Baptiste's six-yard shot levelled it by the break.

Wigan moved out of the bottom three with a hard fought 4-3 victory over near neighbours Blackburn Rovers at the DW Stadium.
