Video referee Lee Mason forgot to draw offside lines on Brentford’s controversial equaliser in a mistake that could have a massive impact on Arsenal’s fight for the Premier League title.
Christian Norgaard was in an offside position when he crossed for Ivan Toney and the goal would have been ruled out if the VAR lines had been drawn.
Victory for Arsenal would have put them eight points clear at the top of the Premier League but the draw means Man City will knock them off the summit if they win today and beat the Gunners on Wednesday night.
