2 promotions, 7 seasons of PL footy, European birth, 2 top 10 finishes with Burnley, developing a few players to be England Internationals is a massive success for a club of our size/expenditure in todays game mate.
It's not what you guys may deem as successful but it is for Burnley FC in the 21st Century. For contrast, look at how VK has done in his first season in the PL comparatively (with much more money being chucked at it).
That's why, may I add, laugh at some of the names that Everton fans come up with that they may want to replace Dyche - some that can't even crack a playoff birth in the Champ, let alone win a division.
