There's no way they'll loan him unless it's with an agreement at the end to buy him. You're more likely to pick up a loan from a premiership team for a squad player. Was this fella playign last year for them when they went down? 
as a 21/22 year old he got 30 Premier League games last year along side 2 other 21/22 year olds and any one of the other 2 CBs they played was not very good
paying £20m for 4th choice CB is not good if you look at it like that BUT paying £20m for a CB that will be at you club and PLAYING for a long time is a great move
6 foot and has real pace , can play as the DM sitter if needed right footed but plays well with both feet
quick defenders happy with both feet opens the door to 3 at the back
if we have the money I would get him over the line now above all over position we need bar GK
