Former Leicester City boss Nigel Pearson says he's not bothered by the Foxes' success.

He said it was a "big shock" to be sacked in June 2015 by the Foxes, who won their first top-flight title under Claudio Ranieri last season.

Pearson, in charge at Championship club Derby County since May, says he found being out of the game tough at times.

"They've gone on and achieved something that really, in the modern game, is impossible," he told BBC Sport.

"I'm delighted for the players and the staff there."

However, he added: "I felt pride - but I was very detached, actually."
