Wouldn't surprise to see those three leave plus Ramirez, Tadic, Yoshida and maybe Fonte. Not to mention some of the young loanees some who have spent years on loan. If they're not going to get the opportunity to step up they will probably move on.
Can't see Saints spending big or progressing either, if you measure progress by league position.
The future of Ronald Koeman at Saints is uncertain to my mind also.
What really worries me most is the apparent lack of promising young players emerging.
Usually an optimist but struggling with that at the moment , have to say.
