BFG is retiring at the end of the year and Kos is starting to break apart (achilles injury) so there are going to be plenty of opportunities for him and Holding, especially if we stick with three at the back.
I actually think he's decent and talented enough to possibly make it. The problem that he and our CB's have is that the way we play will always make our CB's look a lot worse than they actually are - no protection or defined instructions on what to do. You could throw in prime Cannavaro into a lineup and he'd struggle ... and if reports are to be believed, one of the reasons Mustafi wanted out in the summer was because of this.
It's a testament to how GOAT Kos is that he's one of the few that's managed to protect his reputation whilst being a CB for us.
It's a indictment of our incompetence but not our financial thriftiness - I mean we're standing to lose about £100 million of talent at least for free at the end of next summer.
The financially sensible think would have been to sell both of them the previous summer when they refused to commit.
At any rate, I don't see how this is a bad move by the club. As a young talented English CB, Chambers will retain value and it's useful to prevent us losing him on a free or having to sell him at a cut-rate price down the line.
Same thing applies to Welbeck and Ramsey. In isolation securing players like that at the club is a sensible thing to do.
