No bro in terms of market value we're legit top 10 in Europe, according to Transfermarkt. The team just doesn't click together. Omer Toprak, Arda Turan, Volkan Demirel, Oguzhan Ozyakup, Caner Erkin, Hakan Calhanoglu and Gokhan Tore are all (potentially) top class players.

No bro, those transfermarkt values are arbitrary, the value of players in Turkey are inflated. So in terms of those self-inflated arbitrary transfermarkt values (self-inflated values) Turkey can be a top 10, or if you inflate them more it can even be a top 3 league but in reality no one's going to pay those values to you, and no one will pay them the kind of salary they make in Turkey (Ozan makes about as much salary as Yannick Carrasco without accomplishing half of what Carrasco has, so he stays in Turkish league and doesn't develop as much as he would've if he'd moved to Valencia last year instead of Fener).

In true rankings, Turkish league ranks #11.

Omer Toprak and Hakan Calhanoglu are products of Germany, not Turkey, and they play in Bundesliga and for Bayer Leverkusen, that's why they're valuable as Bundesliga is one of the top leagues in terms of difficulty and quality. Other players you've listed aren't as valuable except for Gökhan Töre, he's the only one who can make a transfer at or over 10 million in Turkey.

You can't compare Turkish selection to teams like Romania, Albania, Slowakia etc. But for some reason they're playing way better than us.

Romania are already eliminated from the tournament, they're the first team. And Turkey played stronger opponents than Albania and Slowakia, and their players aren't "primadonnas", they're actually trying to prove themselves and increase their value and earnings, unlike players in Turkey whose values and salaries are already inflated by Turkish clubs and media.
