22nd December 1984 - an eventful top of the table clash at a rain lashed Fratton Park
saw a very late defeat for the U's in a thriller.
United were a goal up thanks to a second half Kevin Brock strike before the hosts hit
back with two late headers from Alan Biley at the Fratton End.
The game will be long remembered after a fan dressed as Santa Claus
invaded the pitch just before Alan Ball's Pompey hit back to win.
Billy Hamilton saw a last gasp effort unluckily hit the woodwork
with seconds remaining.
22,446 were in attendance.
