Holding has been good this season and is still young enough to learn and improve so no need to castaway yet. Having said that I don't see the point in all of Chambers, Mav and Holding alongside Kos, Sok and Mustafi though clearly Koscielny's days are numbered.

We also had another young CB on the bench yesterday out of nowhere who I had never even heard before.

I somehow can't see us going out and spending a load of money on a ready made top CB next summer though.
