I'm really happy with the signing. He's a proven defender, and we will need one in what will be a transitional season for us in defense. He could start if needed, or be a capable backup and keep pressure on our first choice pairing, pretty much what Carra did for us last season.
Whatever pairing we end up starting the year with, it will be important to have the ability to switch things up without putting our season in danger.
Personaly I've always liked him as a player, he's been one of the better Cb's in the world over the last decade. Although he's probably not getting any better at this stage in his career, he should provide a nice option for us to have.
A proven veteran defender can be useful, to any squad in the world.
