Saints fan here.
its a difficult one to get excited about, aye?
I think there’s quite a few caveats, variables and nuances that need to be considered when appointing Russell Martin.
For me, he’s probably a one or two shifts away from being a very good manager. If you put the tactical inflexibility aside, there were times where he showed his nous by changing the formation for some of our games to suit the opposition (vs Leeds twice and vs West Brom twice. He genuinely showed he ‘could’ switch it up tactically and get results - that’s the bit I would hope he’s learned from; it’s not a crime to move away from your philosophy for a game or two.
What holds him back is just that - his overriding, pig headedness to change when his vanity project is falling apart. He takes things very personally when questioned and can be a bit spiky also.
that said, the players seemed to ‘buy into’ his philosophy and if they do, you’ll be ok.
Have my doubts about him being a nice guy though, much like the Swans fan above. The portrayal is different from the reality.
also - can’t see him liking Fatawu or Mavididi; way too front footed and direct for him.
