The coast is all clear for Chelsea as Kai Havertz is believed to have told Leverkusen he wants to leave and the West London club are at the head of the queue for the 21-year-old.
Real Madrid have long been rumoured to be monitoring Kante and Lampard may allow boss Zinedine Zidane to finally snap up his compatriot.
Leverkusen are asking for around £90m for Havertz but Chelsea are eager to haggle the price down.
Kante was recently linked with a move to the Bernabeu for a fee in the region of £70m and any sale would go a long way to bankrolling the arrival of the German ace.
Kante is a former Premier League Player of the Season winner and lifted the trophy in successive years at Leicester and Chelsea.
The 29-year-old has a contract until 2023 and has shown his prowess as a holding midfielder as well as his ability to play a more attacking role in the middle of the park.
With the emergence of Billy Gilmour, the return to form of Ross Barkley and the presence of Mason Mount and Ruben Loftus-Cheek, Lampard may let the Frenchman go.
Havertz dazzled in the Bundesliga season just gone, bagging 12 goals and six assists in 30 appearances.
And if the Blues seal Champions League qualification they are confident a deal will go through, especially with German colleagues Antonio Rudiger and Werner already at Stamford Bridge.
