“As part of this squad, I’ve never known a spirit like it – from the owners, to the manager and his staff, the players and the fans. I want to be part of it for a long time.
“Leicester City have shown nothing but total faith in me since the day I arrived here three and a half years ago and it’s impossible to measure how much that belief has helped me to improve.
