The current stagnant position is down to the board not willing to move with the times, they don't want to invest and see 4th place as their championship, there's no real ambition to challenge the best in the world or become the best, they've taken the defeatist stance and accepted we can't so why bother.
Dein was much more forward thinking and wanted the club to compete with the best, losing him was a bad thing for the club IMO.
