I thought he was decent, at the time I'd say he was probably our best centre half out of Lovren & Skrtel. Aesthetically he looked a lot worse than he actually was because of his bambi legs, sort of similar to Matip where even when he's got the ball under control it doesn't look right.
Was great with the supporters & everyone loved his passion on the pitch but off it he was an arsehole by all accounts. I think it was the pre season tour in 2016 where he took the piss a few too many times and Klopp had finally had enough. Always thought that it was a bit peculiar why PSG would offload their captain at the time who had bags of potential & with hindsight it's pretty obvious to see the off-field issues must have played a big part.
Still have a soft spot for him because as I said, on the pitch he gave a pretty decent account of himself but looking at how his career has ended up it's no surprise why we got rid of him. Actually ended up making a pretty tidy profit on him too so you've got to take your hat off to Edwards & the rest of the people who work on that side of the operation, because it's pretty obvious that he was nowhere near (at the time) a £25M + centre half
