Chelsea went a goal down early on at Stamford Bridge but battled back to secure a comfortable win with strikes from Tammy Abraham, Ben Chilwell, Thiago Silva and Timo Werner.
Kante, meanwhile, impressed in a midfield trio alongside Mason Mount and Mateo Kovacic.
And Lampard admits he has been desperate to keep Kante fit after injuries restricted the French World Cup winner to just 20 starts in the Premier League last season.
The Chelsea manager also believes Kante’s ability on the ball is ‘underrated’ and has praised the midfielder’s performances in the last few weeks.
‘I have made big steps to try and manage his training and games, and making sure we attempt to keep him as fit and ready for games as we can,’ said Lampard.
‘He’s shown in the last couple of games he’s played he is N’Golo Kante.
‘His attributes are incredible, he can play various positions in midfield, he has energy, the ability to win the ball back but also his ability on the ball. That is sometimes underrated.
‘I’m pleased he is fit now and we will keep managing that.’
