I’m not sure about “buy in”.
I’d say buy in would mean having patience and belief in the new approach being the way forward if we want to have a better football team on the park along with the understanding that it may take time to yield results.
Unfortunately, fans are not well renowned for patience and understanding.
We may not be able to fix our issues till next season after the summer transfer window. I’ll be ok with finishing 10th and continuing to play the excellent stuff we have seen so far. Having said that I’m confident of us not being in a relegation dog fight come the end of the season.
As JBA says, “it’s where you finish at the end of the season that defines your season”. It’s not where you are after first round of fixtures.
