Ten-man Arsenal hit back to secure a 2-2 derby draw at Tottenham Hotspur, with Alexis Sanchez equalising 14 minutes from time.
Harry Kane tested David Ospina in the Gunners’ goal twice in the early minutes, as the hosts made a strong start, before the striker rifled an effort over from 25 yards.
Spurs continued to dominate as the half progressed, with Danny Rose a threat as he broke forward from his left-back berth.
Twenty-five minutes in Ospina made a superb reaction save to deny Erik Lamela, as the Argentinian deflected a cross from the right from Kyle Walker towards the far corner of the net.
However, after the hosts had enjoyed by far the better of the game, Arsenal hit the front six minutes before half-time when Danny Welbeck got clear on the left and played the ball across the area.
Hector Bellerin returned it into the middle and Aaron Ramsey arrived right on cue to backheel the ball past Hugo Lloris.
Early in the second half Ospina had to parry away a fierce drive from Walker but soon after the Gunners were reduced to 10 men as Francis Coquelin was sent off after receiving his second yellow card of the game.
Ospina then made a superb goal-line block to deny Kane following a corner, but he had no chance soon after as another corner dropped at the feet of Toby Alderweireld and he rifled a left-footer home from five yards out.
A couple of minutes later Spurs were 2-1 in front as Kane drifted into the left side of the area before curling an exquisite right-foot finish into the far corner of the net beyond the despairing dive of Ospina.
Kane turned well but dragged his shot just wide as the hosts pushed on for a clinching third goal, but they were pegged back 14 minutes from time as Bellerin fed Sanchez and his shot found the corner of the net, despite Lloris getting a hand to it.
Ospina was again the man for Arsenal 10 minutes from time as he plunged to his right to keep out a Dele Alli drive before the Colombian had to react smartly to tip over a Christian Eriksen curler.
At the other end Lloris had to fist away a Sanchez free-kick from 25 yards and Kevin Wimmer made a crucial block from Ramsey to ensure that the game ended level, with a point less than both sides had hoped for.
