I would much rather him play minutes than sit on the bench in the championship. Statwise he has been good for Roda this year, Fotmob thinks their second best player. If anyone has actually watched him play I would be interested in how he has looked. Last year he was rated middle of the pack for a terrible Ross County side (who now sit bottom in SPL2 interestingly).
Is a good player on a mid table Eredivisie 2 team someone a champ team would want to pay a fee for? I'm not convinced. I still expect an Aliga side to come in and pay overs for him to return. Depending on who it is, he may be win another title or may just be a good player. But it seems reasonable to think his career high was the JW medal and back to back titles. This situation was perfect for him, an important player in a strong side.
On the height part, he is short even for those guys mentioned.
All this is to say it always surprises me when people think he would be a difference maker for Aus. Some kind of potential to be unlocked for the national team.
