The Blues are on the brink of appointing Thomas Tuchel as their new head coach following Lampard's dismissal on Monday. Red Bull Leipzig boss Julian Nagelsmann also had key admirers in the Chelsea boardroom, but it was clear the highly-rated coach would not leave mid-season.
Having originally wanted to give Lampard an opportunity to turn Chelsea's season around, last week's feeble loss to away at Leicester appears to have been the final straw for owner Roman Abramovich following weeks of disappointing results.
Sources have indicated that Abramovich, despite preferring to wait until the summer to make a change when more of his preferred replacements would have been more readily available, accelerated his initial interest in Tuchel immediately after the loss at the King Power Stadium after conceding a new boss had to appointed immediately to save the club's season.
Indeed, it is understood Tuchel could have been in place prior to the win over Luton on Sunday but Covid travel restrictions meant Lampard was afforded one more game.
However, initial plans to replace Lampard were spawned during the summer, with the club sounding out potential candidates to take over from the 42-year-old in anticipation of the season not going to plan.
