Heading in his first goal for the club in Cambridgeshire, the defender spoke of his performance and time at the club since joining in the summer.
Coming into the fixture, the towering centre-back kept the armband after another impressive display and was pleased to get the result.
"It was a tough game especially with the heat for a big white guy like me, it was a bit of a struggle.
"But we got the job done and we got the early goal, obviously they got theirs but when I scored we sat back. I think we defended well and got the job done in the end."
On his winning goal midway through the second-half, he explained how it came about.
"I was marking their big tall guy and he was just taking me wide out of the way of everyone.
"So I thought I’d do it with him on the first one and took him out of the way and then the second one I thought he’d think that I’d do it again, but I just made a darting run and got on the end of it."
He added: "It’s good, obviously it’s only my third game but it’s good we work on it in training and I think that it’s going well."
Signing for the club at the start of the month, the experienced player believes the team are getting better after a positive week since his return.
"I think you could see with the Blackburn Rovers game with the confidence and I think we were gelling a bit better and we were getting to where we wanted to be.
"The last few games I think that we have defended well against Exeter City and we didn’t put our chances away, but against Cambridge United we did and we got the three points which is nice."
Taking a leading role in the dressing room now, Wheater kept the message to his teammates simple ahead of the fixture.
"I said to the lads make sure that we get the points to make sure the journey home is a bit better and obviously for the fans as well.
"I’m sure they’ve had a few beers in the sun so it’ll have been a nice day for them too."
