I can remember them years ago doing this one summer selling all of Rodriguez, Lallana, Clyne and loads others all in one go. People thought they'd massively struggle but Koeman came in and signed very well and they made europe in the end.
Problem here is their form from January onwards last season was terrible and they won't be going for top class players as replacements. Someone like Armstrong got a good scoring record in championship but then so did Che Adams and think it took him six months to actually score in premier league, Southampton will be going down if that happens again.
Certainly seem to be in the treading water at prem level stage and that's never a good place to be, only really Palace who seem experts at it and not getting drawn into serious relegation scrap.
