There seems to be a tipping point for clubs like Brentford.
They do well on the back of team spirit, relatively unknown players and adrenaline resulting in promotion to the PL. That's when the problems start.
The squad is 'strengthened' with new players on PL wages which mean the others want more money. Any who are 'too good' are poached by the top clubs and replaced by others who expect PL money. The team spirit suffers and players who'd won promotion find themselves in the reserves. The supporters moan, the momentum goes and relegation often follows.
I'm hoping KLD's forward planning has taken this into account and found solutions.
