The 29-year-old has stressed he “categorically has never gambled on football” and has requested more time to contest the charge having initially been given until Tuesday this week to respond.
Klopp said the striker remains in contention for the trip to Watford.
“You don’t see any influence on Daniel in training, so that’s good,” he said.
“I don’t know, I cannot say actually, anything about the case. It is difficult to get information about it but in training he is completely normal: in good shape, looks sharp, looks focused, but of course it is something you do not want to be involved in.
“But from my point of view, and until someone tells me something different and as long as he trains well, he is 100 per cent in contention.”
