I agree, as much as we want some of those players in reality it probably won't happen. Though as good as Barry is, I really don't think we need him with Alonso playing as good as he has this season.
As long as we keep onto Alonso, Barry would really only play as a utility/backup player either on the left of midfield or at left back and only at the centre of midfield whenever Masch or Alonso are out of action. He'd be a great player as backup but that's it, I don't expect him to hold a first team place and I don't believe he would come in knowing he would play as a back up player.
But yeah back on topic, SWP is a unrealistic target in my opinion.
