The boys in blue will now play the winner of Cashmere Technical vs Coastal Spirit in the other semi-final and will be focussed on what is a great opportunity to end the season with some silverware.
The Rams dominated possession for large amounts of the game at a crowded but chilly English Park, before Max Chretien finally made the breakthrough midway through the second half.
Veteran striker Michael White was the most dangerous player on the pitch in the first half and for much of the game and narrowly missed a couple of early chances.
FC Twenty 11 defended resolutely and grew into the game at times during the second half but Chretien’s goal proved the difference in what was a tightly contested affair.
United’s second half substitute wingers Mark Pearse and Trey Butler were lively when they came on with Butler hitting the crossbar from a cross turned shot as chances for both sides went astray.
The team’s road to the final saw them progressing through the first round via a bye, before beating Waimak United on penalties after a 1-1 draw and then FC Twenty 11 1-0 in the semi.
The English Cup is Mainland Football’s senior mens’ knockout cup, where clubs’ first teams throughout Canterbury compete in an elimination style tournament. Cashmere Technical have won the tournament in the last three consecutive seasons after Ferrymead Bays’ victory in 2016.
Christchurch United has won the English Cup on seven occasions but the most recent of those was in 1991.
