I don't rate Goldson at all. His distribution is terrible and his 1v1 defending laughable. Gets beat too easily. Sample size is large at this point. He's just not very good imo. Katic is ok and has potential but can still look unconvincing. He's another one who struggled to deal with Landon Dykes..
Hellander can't get a game for Sweden who's back-line is beyond average. He did well vs Feyenoord but let's be honest he wasn't up against much. Toiled badly when up against a bit of physicality vs Livingston. Not writing him off as we simply haven't seen enough of him but my alarm bells are ringing.
Can't really comment on Edmundson as he's barely had a chance.
