Manager Gary Johnson conceded his Robins did not do enough to claim any points as Cheltenham lost 2-0 to promotion hopefuls Wycombe Wanderers at the LCI Rail Stadium.
Adebayo Akinfenwa and Paris Cowan-Hall grabbed the goals just before half-time to ensure Johnson's lost the Sky Bet League Two encounter.
"The first goal was going to be important, because up until then we were coping with their strike-force," he said.
"They got a couple before half-time and then it is very difficult against good teams to get the game back. But we didn't do enough.
"We didn't give ourselves a chance because we didn't create enough opportunities and we got beat by a good side.
"The fans want their team to win and if they don't they are frustrated. As a manager you still get frustrated, but you have to keep going and try to get the best out of them, which we have seen on a few occasions this season.
"We've played a very experienced team and they have stopped us creating opportunities. But we weren't good enough to create enough to look like winning the game.
"They took their chances like they have all season. They didn't have loads of them, but they took the two when they come along.
He added: "Akinfenwa is good at what he does and he didn't have much room but he backs into people, spins on a six pence and toe pokes it in. That is what he does.
"I felt we had dealt with him okay, but he is always going to be dangerous and we lost the ball out wide and Bayo does what he does with a little bit of space.
"The second goal they had a man over after we gave the ball away in our own third. I will look at it and I will know exactly what has happened, but we haven't had that much this season.
"If you make a mistake against the top sides they punish you and they punished us."
Johnson made two changes at the break to try and spark his Robins into life to no avail.
"We made changes to try and freshen it up and try and get a different shape," he admitted.
"We weren't winning headers up top and they were dominating. Brian (Graham) came on to do that and Jerell (Sellars) to get on the ball and try and make a pass for somebody.
"But that fizzled out as well. You can't have momentum when then game is broken up so therefore don't be 1-0 or 2-0 down. We've seen it so many times no at home where teams know how to break games up.
"We played a good team and didn't give it a good go - nowhere near. We didn't create enough chances.
"Ilias (Chatzitheodoridis) was probably the only one who was trying to create something so I agree with him as man-of-the-match for us. But I can't remember too many shots or opportunities."
