First problem, Turkey's coach. Fatih Terim is simply not fit to run a team. He has failed in the past and currently as well. But this isn't just all his fault.
Second problem, Turkey's football skills. It is a blown up bubble. Turkey hasn't performed well in neither Euro Cup, World Cup, Champions League or Europe League. We can't play disciplined like the Germans. We don't have the endurance like Russians. We don't have the spicy play like England. Fuck.
Third problem, Turkey's football environment. Face it, almost all famous foreign players who join a Turkish team usually do it for the money and sort of retirement / career ending reason. It is like retirement paradise, because you just have to perform a little bit well and then you can lay around at some beach eating borek and drinking Raki. Nobody will care if you're loved, foreign and famous
I know I am bashing my country too much, but every cup and league I see the same thing over and over and over. We need young talented players, but won't be happening for another 10 years.
Dutchland has the same problem a bit. Also old farts who can't just face that their time is over. (That is why they failed to even qualify for the EC, lol).
