I've been thinking along the same lines for some time.
Ballard is an awesome centre-half, who has shown that he can also be an occasional goal threat. But Mukiele and Alderete are better still.
Hume is a very decent right-back and also adequate cover as an emergency left-back, I remain unconvinced that he is in any way a midfielder. However, Geertruida is way ahead of him in terms of footballing ability and footballing 'nous' and provides a different set of options in terms of covering at right-sided centre-back and defensive midfielder. I think that he and Mukiele could 'dovetail' very effectively on the right side of our defence.
Hopefully Le Bris will have been having similar conversations with Geertruida that he has apparently been having with Isidor, with regard to the futures at the club.
This. Very much this.
