The striker became the club's record signing ahead of their return to the Premier League, scoring five goals in his first eight appearances for the Foxes.
The manager told reporters: "With goals, come expectation levels but I have not noticed much shift in him if I'm being honest.
"He's a quiet-ish sort of man, a really likaable guy. I don't think his outlook will change dramatically. He's certainly had no more pressure put on him from within.
"Leo's settled in very well. He's got off to an outstanding start in terms of goals return but also his all-round play has been excellent. Strikers need enough opportunities and of course like any other player they come in and out of form. It's the same for all players."
