Courtois's never-ending links with Real Madrid have morphed into one of the most intriguing transfer sagas this summer.
He also added that Willian often gets overshadowed by Eden Hazard at Chelsea.
Chelsea are now in a desperate race to sign a replacement goalkeeper before Thursday's 5pm transfer deadline - with Stoke's Jack Butland, AC Milan's Pepe Reina, Atltico Madrid's Jan Oblak and Sevilla's Sergio Rico possible contenders.
"I don't know. I arrived here three weeks ago and have only seen six players", he said.More news: 5 killed, 44 wounded in night of gun violence in Chicago
ESPN is one of the most reliable sources and the rumour also makes flawless sense, as Sarri in his pre-match conference of the Community Shield said that he wants to hear from Courtois that he wants to leave and not from his agent. "My head is here at the Chelsea, but we never know about tomorrow".
Sarri refused to be drawn into commenting on what has been said by Courtois' agent in the past week and insisted that he would have to talk to his goalkeeper himself before a decision is made.
Given he has just 12 months left on his deal, the London club are eager to find a resolution to Courtois' future rather than risk losing him for nothing next year. "I hope this can be a year of victory for us". "I only want people here who are committed".
Courtois did not play in the game, with deputy Willy Caballero experiencing a busy afternoon against an incisive City attack.
Courtois, who has been heavily linked with a move to Real Madrid, was handed an extended holiday after helping Belgium to a third-place finish at the World Cup.
