I don't see it as an attractive option, unless it's a short term month deal.
Word was he won't be fully fit til September/October and if so we will want to oversee his final rehab and conditioning. After that (Oct/Nov) a month getting match fit in the Championship could make decent sense but
beyond that seems very doubtful.
If as stated fully fit is September then competitive football where he can be assessed without potentially weakening our side can only be a good thing. We get to name a new squad at Christmas so hopefully he will have had at least six weeks under his belt and all the matchtime that that entails. Brighton, Bristol, Reading, Brentord and Fulham are all near enough to commute. Maybe he won't need the whole season, but at least we'll be able to assess him properly
