Colchester manager Joe Dunne felt the margin of his side's 2-0 victory over Carlisle could have been greater.
Two goals in the space of six first-half minutes from loanees Craig Eastmond and Jabo Ibehre helped the U's record back-to-back home victories.
Dunne said: "I'm happy that we've got three points. I thought it was a really good learning game for us, in terms of us having to adapt to what another team has done not only once but maybe twice.
"Overall, we scored great goals and we could have scored some more great goals. But there were one or two things that we could have done a bit better. But I'm not going to complain about winning, that's for sure.
"We've said to the players that if we want to have a passing game we'll have a passing game and if we want to go toe-to-toe, we have to do that. Players have to adapt and if it means grinding out results, we'll do that as long as we get positives. But I'm really pleased for everybody and I thought once we got ahead in the game, we could have had more."
Kallum Higginbotham, Mike Edwards and James Berrett all squandered free headers for the Cumbrians in the second half. But Carlisle could not get back into the game, much to the frustration of their manager Greg Abbott.
He said: "I'm not just annoyed that we have not taken a point from the match. I'm annoyed that we haven't come away with all three and that we did not win the game. But it wasn't the sort of game where I could give the players the hairdryer treatment afterwards because I felt that we did so much right.
"We had a bad 15 minutes in the first half where they scored their two goals and we lost our shape, but then we were able to reorganise.
"We could have scored three or four goals in the first 15 minutes of the second half alone. I don't think that I've ever seen a team create so many clear chances and not be able to take them.
"We should have had at least two penalties in the game and maybe three, but that shouldn't have really mattered had we taken our chances."
