The veteran netted the winning goal as the Foxes beat Bournemouth 1-0 at Dean Court on Saturday afternoon.
He told Sky Sports News: "You've got to keep your feet on the ground, we're in a very good position, but you've got to stay grounded.
"It was a great feeling yesterday, it was a tough place to go, but there's still plenty of games to play. We're in a healthy position, and the atmosphere is great and all the cliches you associate with being top of the league are there.
"I'm delighted to be back playing and getting back on the score-sheet."
Leicester host Watford next week.
