Should be a good signing for us. Has great potential and like most of the Southampton graduates, is very comfortable on the ball. His versatility possibly means that he is our 2nd choice RB and 4th choice CB going into the new season. It has been mooted that he will end up as a CB, but I doubt we will start that process any time soon. Needs to work more on his defence, but think Wenger sees a player who is comfortable on the ball as a better fit to be integrated into the team at a young age. Given time he will improve on that aspect, when compared to Jenkinson who I think is a better natural defender, but has struggled to improve his on the ball game and general awareness significantly to stake a claim.
Not sure whether we will look to offload Jenkinson permanently. Feel that we will look to loan him out and if he can get sufficient game time, he could start to develop the defensive side of his game further to possibly become an option for us at CB. He won't get much of a look in at Newcastle with their new RB signing so either West Ham or Crystal Palace out of the clubs who have already been linked. The latter would do a better job of improving him as a defender, but if he really needs first team football, his best bet is to drop down a division.
