Broadcaster Onur Yildiz absolutely savaged Martin O’Neill’s side and claimed they wouldn’t even finish in the TOP TEN in Turkey. And former Besiktas star Nihat Kahveci was hardly more complimentary, branding Celtic’s first-half display the worst he had ever seen from the Hoops and wondering how Besiktas possibly managed to turn such a comfortable night into defeat.

The Istanbul giants arrived in Glasgow unbeaten in the League Phase after a testing opening trio against Marseille, Hoffenheim and Crystal Palace. And for 45 minutes, they appeared to be cruising towards another positive result as Celtic struggled to lay a glove on them.

But the game was transformed after the break. The Hoops cranked up the tempo and deservedly came out on top to spark a furious post-mortem back in Turkey.

And Yildiz led the inquest with an extraordinary rant which somehow stretched from Ottoman history to Vaclav Cerny’s infamous water bottle incident at Celtic Park.

Speaking on BTV, Yildiz fumed: “Samet, look. If Celtic played in our league, the Super Lig, and finished in the top ten, I’ll change my name.

“Look, Besiktas played against such a bad team today. During the first half, Nubel almost got pneumonia. The ball didn’t reach the man.

“So you take the lead in the second half. You’re saying it’s going to be like a tourist trip. A match you’ll win, and you’ll go home happy and cheerful. It’s like a friendly in an Austrian training camp.

“But something happens to Besiktas away from home, and suddenly the fans start tearing their hair out. Look. Corum, Kocaelispor, Kasimpasa. I dare say these are way, way better teams than Celtic.

“The guys came with a 0-3 record. They were coming to get their first point from us. They got their first win against us. So Besiktas played against such a bad team. It’s time we started talking about the shortcomings.

“So it’s over for Besiktas. The Tulip Period is over. First of all, Besiktas absolutely needed to sign a good central defender. The defence is falling apart. At the start of the season, Haric was the only kid who resisted. Apart from Emirhan, the defence is bad. Djalo is bad. Agbadou is bad. Besiktas conceded their first goal because of him.

“We were shouting from the rooftops that they needed a right-winger. There’s no right-winger either. Why did they keep Cerny on today? How did he last so long? He gets a bit more motivated in this game because of some past incidents.

“There’s an incident, I don’t know if you remember, Cerny was playing for Glasgow Rangers. Glasgow Rangers score a goal against Celtic, Cerny pulled a water bottle from the bench and sprayed it at the Celtic fans. That’s why he was booed every time the ball came to his feet.

“He was booed not only because he played for Rangers, but also because of that incident. But Besiktas’ flaws have now been revealed.”
