Look its easy to slag off a poster for making a suggestion.
This is a discussion that should be happening in the early pre season, not if we will be signing bloody Frank Lampard, Steve Sidwell etc...
Carrying on the OP, I think Helan will become our 1st choice LB this season and he is 6ft I believe so not tiny but I have questions over his positioning and marking skills, plus his upper body strength compared to established centre halves.
