He may well be a good addition to the squad and prove to be an excellent investment. However, given that Binden is already at the club, I really don't think pairing him with another young and relatively inexperienced CB is wise. Surely and especially if JLT departs, an older, more experienced 'dog of war' is required at he back, especially if Saturday is a glimpse into how Selles will play this season.
If not Utd will be very soft and most likely get bullied - can you imagine them against Wrexham?
