Arsenal 2-2 Chelsea: Five Things We Learned

Arsenal subsequently began to dominate the play, and Wilshere finally broke the deadlock in the 63rd minute after Courtois had again made a fine save from Lacazette.
Chelsea came from behind to take the lead at 2-1 only ten minutes before the end.
A sweeping crossfield move in the 84th minute saw Zappacosta get the better of Arsenal's inexperienced left back Ainsley Maitland-Niles before rifling in a low cross that Alonso met sweetly to give Cech no chance.More news: Yet another D-Day for Lalu on Jan 24
Arsenal's defense was again inconsistent as the second half began, and Cech had to step in and save a couple Chelsea shots. A weak effort aimed straight at Cech was followed by a thunderbolt courtesy of right wing back Zappacosta, who nigh-on dented the crossbar.
