I've been one of Sakho's biggest fans over the last three years, but it's pretty clear he's not going to make it as a first choice centre back here, nor is Skrtel, in fact Lovren is the only one who's shown enough to stand a chance. From watching us play, it's pretty clear that Klopp likes to play with a centre back who goes forward and attacks any incoming threats and one who stands back and covers (which Lovren did superbly yesterday), Sakho was clearly the one going forward and challenging the ball yesterday, he did it very well 50% of the time, the problem with being a centre back though is that you're judged on the times you royally fuck up, which was far far too often from Sakho yesterday. I think it's pretty clear from watching his gameplay clips at Schalke that Matip has come in to replace Sakho in that role, the question is, will Klopp replace Lovren on the other side? Personally I'm fine with him leaving Lovren their with Skrtel as backup, I'd rather him focus on a goalkeeper, a midfielder and a goal scoring winger, and I believe with a good preseason and some more time training under Klopp, Lovren can begin to rediscover his Southampton form.
