The on-loan striker took his tally for the season to 16 goals in 22 appearances since joining the Sky Blues from Nottingham Forest in August.
It was the fourth time the 25-year-old had netted a brace this season and it left the former Southampton player desperate to score a treble.
He told the club's official website: "I was dying for that hat-trick but it wasn't to be.
"I haven't scored one for the club yet and I missed a couple of chances to do that.
"Most importantly, though, everyone is chipping in at the moment. Adam Barton and Franck (Moussa) scored two great goals and it is important that it isn't just me getting the goals.
"I am really looking forward to each game at the moment and the side are full of confidence which always helps me out."
