United could return
However, The Express has revealed that Manchester United are expected to renew their interest in the defender in the summer, but it remains to be seen as to whether they're able to conclude the deal.
It appears, then, that, despite the transfer failure, Louis van Gaal and Co. are taking youth development seriously at the Theatre of Dreams as they go in search of long term success.
Manchester United's Dutch boss has handed a number of young players the opportunity to showcase their talents in the first-team this term, with the likes of James Wilson, Tyler Blackett and Paddy McNair all staring for the club.
Wilson and McNair both featured in the Red Devils' victory over Cambridge United last night, with the former finding the back of the net in the 3-0 win.
There's no doubt about it, with Van Gaal in charge at Old Trafford, United's youngsters will continue to be handed first-team opportunities.
