From a guy I know who knows Sakho, so take it for what it is. But Sakho was given several warnings for Meeting up at wrong places and even delayed a couple of meetings during last years US tour. I think he pissed Klopp way off during the Whole trip so Klopp eventually sent him home. Sakho just wrapped his things up and went home with no more fuzz. Then Klopp tried to ship him off to loan last season with Sakho denying it as he wanted to fight for his place. I think he also fullfilled his contract well when training with the U23's by showing up and putting in the work. However before relegated to U23 Klopp told his agent that he would be given a proper chance if he changed the attitutde, only for Sakho to give Clear order that he wasn't here to "suck anyones Dick". So not easy to say but it seem Beyond repair and Sakho will not play for Klopp again accoridng to the same source.
