Manager Mark Robins praised his side's hard work after goals from Marc McNulty, Jordan Shipley and Michael Doyle helped City to a 3-1 win over Cambridge United
The win means City extend their winning run at the Ricoh Arena to seven games, a run that started on the third of December.
"This result is really good and that record is brilliant," said Robins.
"The first half was okay and the second half was scrappy. The pitch was in a really poor condition and we struggled with it at times.
"Cambridge had a really good go in the second half and we had some really nervy moments until we go the third.
McNulty opened the scoring for the Sky Blues after just ten minutes, and played a big part in the second when he charged to the byline and played a delicate cross for Shipley to head home at the far post.
"McNulty was outstanding and so was Max Biamou. The pair were brilliant all night.
"We struggled to get going becuase the tempo was not right but once we got ontop of that we got the goals.
"McNulty's finish was outstanding. The second goal was a good move from Sparky and it gave us a little bit of breathing space.
"The amount of effort that we put in on Saturday has taken it toll on us. Give us a few days recovery now before we face Forest Green. If we can get a result at the weekend then that sets us up really nicely.
"They have worked hard for these three points and that is a good trait to have. You are not going to get free flowing football all the time and Cambridge are a side who have had ten days off. They were a fresher team and I don't think that was too evident because we were okay."
He addded: "All-in-all, a really good nights work and onto fifty points now. We are looking ahead to Saturday."
