Arsenal midfielder Declan Rice struck in the second half to cancel out Bruno Fernandes's free kick but Mikel Arteta's men could only muster a 1-1 draw with Manchester United on Sunday in a big blow to their Premier League title chances.
Second-placed Arsenal trail leaders Liverpool by 15 points but with a game in hand, while Manchester United are 14th on 34 points.
The first half was far from a classic with Arsenal dominating possession but with few chances for either side before Fernandes finally broke the deadlock seconds before half-time and against the run of play with a brilliant free kick that sailed over the wall and past the outstretched hands of goalkeeper David Raya.
