Matip is a RCB which suggests Skrtel and Lovren likely to miss out?
Although Lovren prefers to play LCB.
I think with Kolo leaving it will mean we will go into next season with Matip, Skrtel, Sakho and Lovren as the four cbs, very difficult right now to say who will start in the first game of next season. But I'd say that depending on how he settles, the fact Jürgen will know him and has spoken about our need to need a winner of a header back there then he will be being brought in in mind to be a starter. Naturally with Sakho/Lovren on the left.
Personally not seen much of him but Jürgen will have done
In games where the opposition being a massive areial threat you may even see him in holding mid in front of Sakho and Lovren
Add Moreno, Smith, Flanno, Clyne for full backs I don't see any more business done back there over the summer personally
