Waine? Kosta? Payne? Roux?
Waine & Payne were in the Nov squad and are almost certainities come March. In this form Kosta replaces Champness. Roux unlikely I'd say - he's never really been in the picture with Hay or Bazeley. He'll need to be a real standout in the ALM the next few months, to give himself any chance.
I can see Bindon being given a go at RB (played there a bit lately for Reading in League One), as Payne's backup in the UAE. Being so young he should have plenty of upside, whether that's at RB or CB. Or they may slot Tuiloma across there again. Kirwan (Congo) & Tuiloma (Australia) started the Oct games at RB. Payne both games in Nov, with Bindon basically the backup. Payne (Sweden) & Billy T (Qatar) shared the June games.
