I don’t think that’s an accurate summary of what he’s saying. The “younger fans” comment surely relates to what they’ve seen us achieve in more recent years compared to say 60’s to 80’s.
It’s more about lambasting players - and it’s always happened before someone jumps in with both feet - week in week out even during games followed up by the same old same old afterwards. He is improving but personally l feel the improvement needed to keep him on is unlikely. I get his form gets to some, whether it’s frustration or, as at least one poster has said, hate but the £20+m reasoning is bollocks. The club - whoever was involved - has the blame for that, not the player.
Plus one has to bear in mind the attitude towards the club in general from some posters is permanently negative. See Cannon for the most recent example.
