As far as third choice defenders whose main role is to sit on the bench goes, Klavan has been a delightful addition to the squad since he arrived in 2016. He's not, and never has been, an elite defender. But he's good enough to come in when required and look solid, and solid he looks most of the time. Has a nice left foot too, which is a bonus.
Honestly, I'm quite fond of Ragnar.
