Returning to the subject of central defenders. I would venture to suggest that Luca has had probably four or five bad games for us similar to how it seems he performed on Saturday. I personally don't think that's too bad a ratio.
As for putting him in the team in place of Sam Heathcote, are you REALLY asking why?
We were playing FGR with the mobile mountain Jon Parkin (incidentally also a VERY good player) so do you select your senior CB who has, in general, played well in the vast majority of the games he has played for the Club or an 18 year old with two or three starts at this level? Does anyone remember what the experienced Jefferson Louis did against the comparatively inexperienced Scott Leather in the Play off at Brackley??
Had Masha been fit he would be the ideal guy to mark Parkin but he wasn't so Luca was, on balance probably the best option
