I can’t see a scenario where Martin will opt to play in a way that would utilise him. Could be wrong of course but unless he is far more adjustable in his way of playing I can’t see him ever choosing the “lump it to a big man” strategy in games, so he won’t be used.
He’s in the same category as Charly unfortunately/fortunately depending on your view. The club have sided with Martin so players who don’t fit in will leave. Charly is obviously the disappointing one as he clearly has something, but it is what it is.
