Arsenal's seismic victory over West Ham may be the defining moment of their title charge. The Gunners required a late goal and a contentious VAR review to overcome the relegation-threatened Hammers in a dramatic London derby.
If ever there was a match to convince fans the 22-year wait for a league title is ending, this was it: a dysfunctional, ugly performance where injuries and tactical missteps allowed West Ham into the ascendancy, before Leandro Trossard-who hadn't scored in 26 games-swept home a deflected finish with seven minutes left.
More drama followed when Callum Wilson's would-be 95th-minute equalizer was disallowed after a four-minute VAR review for a foul on goalkeeper David Raya.
Manager Mikel Arteta praised his team's courage and the referees for a "brave" decision. "What a moment, what an afternoon, what a week," he said.
Manchester City's draw with Everton last week now looks damaging as they run out of games to close the gap. Arsenal lead by five points with just two matches remaining-against already-relegated Burnley and Crystal Palace.
Arsenal's season also includes a Champions League final against Paris Saint-Germain. But for now, all focus is on securing the domestic crown.
Arteta says the team must live in the present and focus on Burnley. The fateful nature of Sunday's victory has set this group firmly on course for immortality.
