Giroud rescues late point for Arsenal while Toure returns with a brace for City
Arsenal secured a 1-1 draw against Manchester United with a powerful late header from substitute Olivier Giroud at Old Trafford to leave home boss Jose Mourinho fuming.
Mourinho looked to be on course for another victory over old rival Gunners boss Arsene Wenger when Juan Mata fired the home side into a deserved lead on 68 minutes in Saturday's lunchtime kick-off.
However, as the clock ran down into the 89th minute, Giroud rose at the far post to head home fellow substitute Alex Oxlade-Chamberlain's cross to earn a share of the points with what was Arsenal's first attempt on target.
Mourinho was incensed earlier in the match when he felt his side should have been given a penalty when Nacho Monreal hauled down Antonio Valencia, referee Andre Marriner waving play on.
The draw left U nited in sixth placed, six points behind fourth-placed Arsenal.
Manchester City moved level on points with leaders Liverpool, second now only on goals scored, after Yaya Toure netted twice in a 2-1 win at Crystal Palace.
Following a minute's silence before kick-off in memory of the victims of the Croydon tram crash, Toure marked his return to Premier League action for the first time this season with the opening goal on 38 minutes.
Palace were level on 66 minutes through substitute Connor Wickham.
City, though, left Selhurst Park with all three points when midfielder Toure converted a corner from Kevin De Bruyne with seven minutes left.

And Nigeria forward Anichebe made it three goals in his two league games when he added a third on 82 minutes.
Sunderland defender Papy Djilobodji was sent off for a second caution during the closing moments.

In Saturday's late kick-off, Harry Kane scored a stoppage-time penalty as Tottenham came from behind to beat West Ham 3-2 at White Hart Lane and preserve their unbeaten Premier League record.
The Irons went in front rather against the run of play on 24 minutes through a header from Michail Antonio.
Harry Winks, the 20-year-old midfielder making his first Premier League start, equalised from close range six minutes into the second half.
However, Spurs soon fell behind again to a penalty from Manuel Lanzini after 68 minutes.
But, just when Mauricio Pochettino's men looked set to suffer a league defeat for the first time in 12 matches, fit-again striker Kane struck in the 89th minute.
And there was still time for a winner, which Kane provided from the spot after a foul on Son Heung-min to move Spurs within a point of north London rivals Arsenal.
