Arsenal's recent resurgence was checked by a stubborn Crystal Palace, who claimed a hard-fought point from a forgettable encounter at Emirates Stadium.
Tagged as relegation candidates as little as three weeks ago, the Gunners came into the game off the back of four straight wins in all competitions, but were unable to find their way past the well-drilled and disciplined visitors.
For a side in such good form, Arsenal were a disappointment going forward, their best effort at goal a shot on the turn from Alexandre Lacazette into the side-netting.
Their only other clear-cut chance was an angled shot from Pierre-Emerick Aubameyang that Vicente Guaita palmed away.
