Arsenal secured their second Premier League win under Mikel Arteta on Sunday as four second-half goals condemned Newcastle to defeat at the Emirates.
Arsenal held the majority of possession and created more chances than their visitors in the first half but failed to break down the Newcastle defence.
It was not long after half-time that Pierre-Emerick Aubameyang broke the deadlock, however, heading in from a precise Nicolas Pepe cross.
Pepe added his name to the scoresheet just three minutes later, finishing after some impressive footwork from 18-year-old teammate Bukayo Saka on the left wing.
Mesut Ozil completed a fine Arsenal move in the 90th minute to seemingly round out the scoring, but Alexandre Lacazette hammered home the fourth in added time.
Arsenal's only other league win under former Gunner Arteta was the 2-0 victory over Manchester United on Jan. 1, with the north London side drawing all four of their Premier League games between then and Sunday's hosting of Newcastle.
