6th and 7th is just fine as long as it's on an upward curve, the concern is, can we hold on to player without CL?Why isn't 7th and 6th ok? And note the upward curve, unlike Martinez who just got worse by the season.
Pochettino only managed 8th in his first full season with Southampton, with a win rate of just over 38%. Koeman has finished 7th and 6th during his two seasons in charge, with a win rate of just over 48% - with a lot of their best players having left.
6th and 7th is not fine if on a downward curve, a la Martinez' 5th and subsequent downward slide.
Forgive me, I'm last with stats sometimes - is 48% any good?
