Chelsea are in talks with Mauricio Pochettino to take over as manager at the end of the season, the PA news agency understands.
A deal has yet to be signed but Pochettino is closing in on his first role since leaving Paris St Germain in July, succeeding interim head coach Frank Lampard.
Chelsea have three Premier League fixtures remaining – against Manchester City, Manchester United and Newcastle – and want their new boss in place once the campaign is over.
Graham Potter was sacked in April and while Julian Nagelsmann was the initial favourite to replace him, Chelsea turned to Lampard to see out the rest of the season in his second spell as manager.
Potter was jettisoned just seven months into a five-year contract but the club has also struggled under Lampard, who at one stage oversaw a six-game losing run in all competitions.
Former Argentina international Pochettino enjoyed a popular five-year spell as Tottenham manager, guiding Spurs to the Champions League final in 2019.
If – as expected – he is appointed by Chelsea, the 51-year-old will inherit an expensively assembled but under-performing squad who will not be competing in Europe next season.
