LONDON — The quadruple of winning the Premier League, Champions League, F.A. Cup and the League Cup has never been achieved in England.
Seven years ago, Arsenal became the Invincibles when they went through the league season unbeaten. The Gunners remain in contention for the Fab Four after a 3-1 F.A. Cup triumph over Leeds on Wednesday kept them on course for an unprecedented Grand Slam after six trophyless seasons.
With Barcelona still to come in the Champions League, a domestic treble is a more realistic challenge, but the Gunners will rarely have a better chance of bringing the first silverware to Emirates Stadium.
