Former Bayern Munich manager Julian Nagelsmann was the favourite for the Chelsea job before he withdrew from the running on Friday with Mauricio Pochettino now the favourite.
According to Daily Mail, Nagelsmann is understood to have been under the impression that the job was his and that talks were a formality.
The report adds: “However, unease grew following a succession of meetings, and reports that managers such as Mauricio Pochettino and Vincent Kompany were also being considered.
“On Friday, with doubts growing, ex-Bayern Munich boss Nagelsmann decided to withdraw.
“Former Tottenham manager Pochettino, who is thought to have seriously impressed during discussions, is now widely expected to succeed Graham Potter and a decision is on the cards in the coming days.”
