That would leave us with 3 right footed full backs, even though Santon is good on the left and Clyne has played there it's still awkward.
Aye, don't think I'd want both. I have no idea about Pieters' quality, but I definitely want us to get a left footed defender I'f we are going for Debuchy or Clyne. If We get a new RB then obviously Santon is LB, wouldn't feel happy just having Ferguson as back up. A LB/CB would be ideal. We'd have RB's falling out our arsehole.
We're obviously not getting both in, but it's abundantly clear from his decision making at the tail end of the season that Pardew considers Santon as a left back predominantly. One would assume Santon has been asked what his favourite position is so has had some say in the matter.
