Ralf Rangnick was reportedly offered the Chelsea job on an interim basis until the end of the campaign following last week’s 2-0 defeat to Brendan Rodgers’ Leicester City.

But the 62-year-old tactician snubbed the west Londoners because of the length of the contract.

Frank Lampard subsequently lasted one more match, a 3-1 victory against Luton Town, before being sacked.

According to The Athletic, major concerns were raised over Frank’s future within the Chelsea board, following the 3-1 loss to Arsenal on Boxing Day.

And the defeat to the Foxes last week proved to be the final straw, with a ‘furious’ president Roman Abramovich deciding to begin the process of recruiting the Englishman’s successor.

Determined to find a German-speaking manager in order to get the best out of expensive summer signings Timo Werner and Kai Havertz, Roman’s first port of call was the highly-rated Ralf.

In spite of being free, having left his position as head of sport at Red Bull last summer, Rangnick turned Chelsea down, however.

It’s claimed that he was not happy with Chelsea’s proposal of a contract only running until the end of the term, despite Chelsea’s plans to elevate him into a different role come the summer.

They also tentatively explored the possibility of recruiting his RB Leipzig successor Julian Nagelsmann but were very quickly knocked back.

In the meantime, Chelsea’s midfield prodigy Billy Gilmour is reportedly expected to go out on loan before the end of this month’s transfer window.
