On this day in 1971, Arsenal’s replay against Portsmouth in the fourth round of the FA Cup was postponed due to a waterlogged pitch.

The Gunners had drawn the first match on 23 January 1-1 at Fratton Park. A League defeat to Huddersfield meant the pressure was on for the visitors.

Arsenal went 1-0 up through a Peter Storey penalty before Mike Trebilcock equalised in the last minute.

Instead of the 26 January, the replay was finally held on 1 February, which the Gunners won 3-2 with goals from Charlie George, Peter Simpson and another penalty Peter Storey. Saying this, Pompey went 1-0 up within six minutes and put up a good fight.

Arsenal went on to beat Liverpool 2-1 in the final, with goals from Eddie Kelly and Charlie George, and clinch the first League and FA Cup Double since Bill Nicholson’s Spurs 10 years earlier.

Since the days when Bertie Mee was boss, winning the Double isn’t such a rarity, as Arsene Wenger has won it twice. However, it’s still quite rightfully seen as a massive achievement in English football.
