Liverpool manager Jurgen Klopp has said Chelsea will not be able to sustain their level of spending since the arrival of owner Todd Boehly.
Chelsea completed their fifth signing of the January transfer window on Saturday when they beat Arsenal to the signature of Mykhailo Mudryk -- a deal ESPN sources have said is worth around €100 million.
The west London club have also welcomed Joao Felix from Atletico Madrid on loan, Benoit Badiashile from AS Monaco, Andrey Santos from Vasco da Gama and David Datro Fofana from Molde.
On Saturday, Chelsea travel to Liverpool, who have signed just one player this window -- Cody Gakpo from PSV Eindhoven -- and when asked about the difference in spending at a news conference on Friday, Klopp said: "I can't see investment stopping in the future, so that means we have to do it as well.
"I believe in coaching, developing and team building 100%. But meanwhile the managers out there, they are all good and they believe in that as well.
"So if they start spending then if we don't spend, you will have a problem. I am not sure Chelsea can do that for the next 10 years though."
