Well if you've that much money you could get someone pretty handy, Cristian Zapata (Udinese) has always been absolutely class for me, failing him Kamil Zayatte is solid can be picked up for a pretty reasonable price. If neither of them can be procured have a good look through the free transfer market, i have known Demichellis or Mexes to be out of contract after season 1, give them a go. As for your backup keeper, have a go with Arsenal, Almunia and Fabianski are OK backups and Arsenal generally sign someone better pretty quick, meaning they'll probably be surplus to requirements.
