He looks like the perfect defender, and at 22 he will just get better and better. He's adapting to the system this year and is already looking pretty good at times.
He's good with with both feet, strong, skilful, can tackle and pass and now he's banging goals in too.
Would be interesting to compare his level and development with Stones at that age, Josko may well be ahead of where Stones was at 22, and if he can avoid injury problems then he could replace him when the time comes, and be one of the best defenders in the World
To me he looks like a cross between Kompany & Stones somehow.
