Liverpool boss Jurgen Klopp has urged for patience over doping allegations against centre-back Mamadou Sakho.

The France international has tested positive for a banned substance following a UEFA drug test, and has reportedly decided not to challenge the result, but Klopp says it is far too early to pass judgment on the matter.

Klopp said: "At this moment there is nothing to say, what we are all doing is collecting information to clear the situation as much as possible and then we have to wait until the next steps.

"We can't force anything, we have to wait.

"What we have done so far is to do what we think is right, and we will now have to wait."
