Harry Redknapp believes N’Golo Kante is yet to show his worth since leaving Leicester City to join Chelsea.
The French midfielder was a key part of the Foxes’ title-winning side last term, in his first season after arriving from Caen in a £5.6m deal.
He made 40 appearances in a City shirt before playing four times for the hosts at Euro 2016.
A £32million move to join Antonio Conte’s Stamford Bridge revolution followed and the 25-year-old is yet to find his feet in west London.
