It's hard to take too many lessons from Arsenal's 5-2 win at West Ham. Ultimately, it was a game that showed the best of the Gunners and of the Premier League.

Saka created Arsenal’s first two goals, with his 10th-minute corner headed home by Gabriel, before the England winger laid it on a plate for Trossard to tuck in a second before the half-hour. In so doing, Saka became the first player to reach double figures for assists across Europe's top five leagues.
