It has been reported that a fat-burning substance was detected in the Frenchman's 'A' sample and he now has until Tuesday to decide whether to accept the charge or ask for a second 'B' sample to be analysed.
When asked about the issue after today's match, Klopp said: "I'm really limited what I can say. There's is an official statement and there's nothing else to say.
"It's not the most easy situation that's for sure, but maybe we can say more when we know more maybe next week."
Sakho is technically still available to play, but Liverpool and the player have decided that he is not be available for selection until the investigation is complete.
