Welcome to The Briefing, where, every Monday, The Athletic discusses three of the biggest questions posed by the weekend’s Premier League action.This was the round when Liverpool fans will hope the Alexander Isak era finally started, Erling Haaland reminded everyone (again) that at least one global superstar plays in the Premier League, and free-spending Tottenham Hotspur got a bit closer to scoring their first goal of the season. Elsewhere, Crystal Palace won at Fulham to notch their first win and keep their hosts pointless and Newcastle United rallied to earn a point against a potent but porous Bournemouth, while Brentford-Sunderland and Brighton & Hove Albion-Leeds United both ended up as “fair enough” 1-1 draws.But here we will discuss Arsenal’s win against Chelsea in a wonderful London derby, Marcus Rashford’s contribution to an entertaining 2-2 draw between Everton and Manchester United, and Hull City’s continuing mission to destroy xG’s credibility as a meaningful metric.Gameweek 3 results…Friday
