FA Cup
As a brand new club Crystal Palace had to qualify for entry into the first round proper of the FA Cup. In the first qualifying round Palace were drawn at home against Clapham. The match saw Palace run out 7–0 winners, with William Watkins scoring the first ever hat-trick. The next round saw Palace overcome the 2nd Grenadier Guards and earn a draw against Chelsea in the third qualifying round. Chelsea at the time were a big draw, fielding the famous goalkeeper, William Foulke. Sadly, Chelsea were obliged to fulfil a League fixture on the same day, and chasing promotion from the Football League Second Division, decided to concentrate on the league. They fielded a reserve side against Palace who duly ran out 7–1, with Watkins scoring another hat-trick. The ease of this victory saw the FA change the rules to ensure clubs always fielded their strongest sides. Palace then dispatched Luton Town in the fourth and final qualifying round to ensure a place in the First Round Draw. Here they were paired with Blackpool, and the tie was eventually settled in a second replay at neutral venue Villa Park after both teams failed to make home advantage pay.
