I don't think anybody - nobody at all - can lay any blame whatsoever at Ancelotti for the defeats to City and Liverpool. He played the strongest team available to him, albeit made up of players proven way out of their depth at this level, and even put an attacking line up (on paper) out against Liverpool's reserve under 21s.
He took off players who were stinking the place out, namely Sigurdsson and Walcott, yet even their replacements barely had a touch of the football. Richarlison visibly game up after about 70 minutes, and who can blame him with those players behind him?
If he isn't given substantial funds and the chance to offload a large chunk of these players then, even if we're relegated, he should bear zero blame. Not even Klopp could get a tune out of this squad. In fact, there will have been no point at all in getting Ancelotti if he isn't given the opportunity to revamp the squad entirely.
