Ndidi joined the 'Foxes' from Belgian side Genk in January 2017 for a fee of £17m, but such have been his performances in the engine room that bigger clubs are starting to sit up and take notice.
According to a source close to the player, Manchester United, Liverpool and Arsenal are all monitoring his progress, with Arsene Wenger's side the most interested.
"There has been so much interest in him. He is going to be a top player and Arsenal have been in contact," the aforementioned source told English publication 'The Sun'.
"They want to sign him this summer.
"Arsene Wenger is a manager he admires a lot and his friend Alex Iwobi has told him lots of great things about the club.
"But there is no shortage of offers. Liverpool have shown strong interest and (Manchester) United."
Nidid has been a key player for Leicester this season, making 36 appearances in all competitions.
