The Foxes were 2-0 up before the end of the first half, but had to defend a one-goal lead for the last 30 minutes following an own goal from Paul Konchesky.
Speaking after the match, the manager told reporters: "Today was about being patient. Early goal changed complexion, looked dangerous, disrupted their game plan, but they were dangerous too.
"[We] would like to close games out more efficiently. Open game, both sides tried to be constructive. Got 3 points, that's all I'm concerned with."
The result has left Leicester third in the Championship table.
