Not exactly enamored with this signing, but I wont judge till I've seen him play in an Everton shirt (providing rumors are true) obviously.
At the end of the day we do need back up there, and it doesn't seem that he would be too arsed sitting on the bench.
Who knows, perhaps the fact that he only recently won his first international cap suggests that he has progressed well as he has gotten older and is at a good stage in his career at the moment.
I hope along with this signing though we get another more established center half in, preferably with premier league experience and of course keep hold of Stones.
