Chelsea's clash with Leicester on Saturday saw N'Golo Kante up against the club he helped win the Premier League title last season.
Here, we take a closer look at the France international's man-of-the-match display at Stamford Bridge.
The 25-year-old illustrated why Blues boss Antonio Conte stated that the midfielder was a 'great buy' prior to the game.
Whenever his defensive midfield partner Nemanja Matic pushed forward, Kante was on hand to stifle any counter-attack threat posed from the visitors.
Kante consistently offered an outlet for Chelsea's back three when Leicester pressed high up the pitch, particularly in the second half. The Frenchman proved that his costly error at London rivals Arsenal was a blip.
The diminutive midfielder was confident on the ball, dishing out an array of passes throughout the game.
He rarely conceded possession and linked up well with Matic as the Frenchman was on a mission to erase his shaky performance at the Emirates a few weeks ago.
A neat chip into the box almost saw Chelsea extend their lead when they were 2-0 in front and despite creativity not being Kante's forte, the 25-year-old looked comfortable with the ball.
Relationship with Nemanja Matic
Both midfielders looked all over the place against Arsenal and despite Chelsea's win at Hull before the international break, the pair did not mesh well but on Saturday, they gelled superbly to add steel to Chelsea's midfield.
The pair outplayed and outworked Leicester's midfield and snuffed out any threat through the middle of the park. The Premier League champions were largely restricted to long-range efforts as Kante and Matic interchanged positions well.
Kante looked back to top form in arguably his best display of the campaign in Chelsea colours while his former team were ineffective and lost in all aspects of the game.
If Kante can produce this type of form game to game in the Premier League then Chelsea will certainly be title contenders, or qualify for the Champions League at the very least.
Inconsistent performances have overshadowed Kante's move to Stamford Bridge but he will have quietened critics after Saturday's display.
