The Reading boss was determined to take his side to Old Trafford in the 4th Round - the prize on offer to the winners of Tuesday night's 3rd Round Replay at the Madejski Stadium.
Robbie Keane made sure we would be making that trip on January 27 with a reaction finish in the 15th minute after Adam Federici had tipped Younes Kaboul's header onto the crossbar.
The woodwork featured heavily on the night - Stephen Hunt went closest for the home side as late as the 81st minute when his dipper came back off the framework while Federici denied Steed Malbranque a fine second goal late on when he touched his volley onto the crossbar. Federici also saved well from Jermain Defoe in the first half and few could argue we deserved the win.
Coppell said: "We had a game plan to keep it tight in the first half and then switch to a 4-4-2 system in the second half.
"We were 1-0 down at half-time but I felt we were capable of scoring goals, we had opportunities and upset their rhythm in the second half.
"Tottenham have some terrific individuals with ability, pace and speed of thought but we created opportunities and I was pleased with our performance.
"We wanted to win. We wanted the chance to go to Manchester United and to play on that stage against some of the best players in the world, the thought of it makes the hairs on the back of your neck stand up. I'm disappointed we didn't go through."
Asked if he thought we were capable of winning the FA Cup, Coppell responded. "Are Tottenham capable of winning six games? Yes. Are they capable of going to Old Trafford and winning? Yes."
Steve Coppell admitted he was bitterly disappointed to lose Tuesday night's FA Cup replay.
