Too early to say just yet for Thiaw. Botman is class and hopefully not made of glass. Thiaw looks as though he could be class but not played long enough to decide.
Think the big plus is that Botman and Thiaw complement each other. Thiaw has the pace that Botman lacks. When Schar and Botman play together we lack pace in the middle of the back four.
This was kind of along my line of thinking - a great pair but who would I prefer in a partnership or in the middle of the other defenders and although it’s early days I think it’s Thiaw - based on his pace in comparison. But they are both very good in all the key defending metrics, probably to close to call.
