'But we are lucky enough to have them under contract and we try our best to make certain they are happy here and satisfied with everything Crystal Palace can provide for them.
Kante, a two-time league victor and a key member of France's World Cup-winning campaign in the summer, told reporters that part of the reason he penned a new deal was down to his improvement as a player in his short time under Sarri's stewardship this season.
World Cup-winning French midfielder N'Golo Kante has ended rumours about his future after he signed a new contract at the club.
The Bianconeri have, in fact, intensified their pursuit of the 21-year-old, having started "compiling a dossier" on the Manchester United superstar. Now he has to improve in the last 20, 25 metres. However Italian publication Corriere dello Sport have reported that Pogba wants out and has told his former Juventus team-mates that he wants to return to Italy.
Kante has now extended his contract with Chelsea by five-years, which is testament to his commitment to the cause at Stamford Bridge.
"We don't have players I can say are out of the game tomorrow, we have a huge 23 group to choose for tomorrow". When reminded of this and asked whether there was any prospect of Sánchez departing, Mourinho said: "I don't think he will leave because he never told me that he wants to leave or isn't happy to stay".
"I went (to) fundamentally be with Lukaku, to see his situation and his injury", said Mourinho. For example, the young lad Luke Shaw, who is the left-back of the national team, who arrived there [at United] two years before me.
Two-years on, Kante now has another Premier League winners' medal under his belt, as well as being a world Champion with France.
"N'Golo for us is not just an important player for us, he is a determined player for us", Sarri added of Kante.
'I can do better and he can do better and all the other players can also do better'. They are top class internationals in top class teams.
