Liverpool boss Jurgen Klopp has voiced his frustration at changes to the fixture schedule which he believes have put unnecessary demands on his side.
The German may have been named September's manager of the month but his mood changed quickly after learning of his side's fixture changes over the Christmas period.
The home match against Manchester City has been moved back to a 5.30pm kick-off on New Year's Eve ahead of a trip to Sunderland at 3pm on January 2, leaving them less than 48 hours between the two.
"Now I have seen the fixtures and I am not too happy," said Klopp ahead of Monday's clash with Manchester United.
"Forty-eight hours is an interesting idea but less than 48 hours I can't believe. I learn more and more about this league and maybe I've to ask someone if we can ask if there will be another time for us at Sunderland.
"Our job is to do everything we can to win games. I understand tradition - I would never say Boxing Day is not a good idea as I love it and I have absolutely no problem (playing then).
"But two days between, there should be another possibility."
