It's unlikely he'll make it here but its not exactly uncommon for players to struggle on their first loan either. It's so different in physicality in league two from anything he'll have been used to. Walsall also had a very, very good strike force for that level so it wasn't really a good loan choice by the club - he was always going to be up against it for minutes with no first team background.
By way of comparison Tom Fellows spent a season being a very unremarkable squad rotation player for one of the very worst teams in League 2, but then was one of our better players the following season.
