The decline of Eastern European football over the last 25 years has been massive, except Croatia and Serbia I just don't see quality being produced on a constant way.
Obviously Bulgaria more evident, but it's clear post Berlin Wall fall while being good at a political level, it surely wasn't great for this countries at sports level.
By the way, the level of European NT's is quite low at the moment, even looking at Germany and Italy now and what they had in the past it's bonkers.
Certainly don't see quality for European Championships with 24 teams, think next Copa America with the United States also there will be better to watch than the Euros, a mistake to expand it to 24 teams.
The main problem in Bulgaria is the astonishing ammount of corruption and fixed games under the rule of Borislav Mihaylov.
Actually our kids are very decent, our national teams for 12-14-16 years old are always performing well.
Something breaks for them the moment they need to make the transition to men football.
We've had a bunch of good players who actually got into decent European teams but they never made the next step.
The last Premier league appearances we had were an uninspiring loan of Stanislav Manolev at Fulham (hey at least he got to do the harlem shake with them...) and a complete disaster for Aleksandar Tonev at Villa.
He had the chance to prove himself in Celtic after being a joke in the PL (every time he recieved the ball he opted to shoot, no matter the distance, angle etc. Did hit a few fans in the process!), but he was dismissed for being slightly racist (he isn't racist he's just stupid. But it doesn't work like this in the civilised world..).
Bulgaria has talent but we don't have the tools to develop our players. Because of the corruption and chaos in the football union.
Wish we could find our way like Croatia did.
Believe it or not, 20 years ago we were beating the likes of Croatia, Belgium etc for fun.
