Uuups, sorry for swopping AEK and PAOK.
Tumba (Tumbakovic) is not exactly my favorite coach. He is very popular in Yugoslavia among Partizan fans since they view him as the main reason partizan was dominant in the Yugo-league in the 90s. In my view, Partizan success was primarily due to a vacuum created by the departure of the Red Star's famous players (Savicevic, Prosinecki, Jugovic, Mihajlovic, Pancev, Belodedic, Lukic, Drobnjak and later Kovacevic and Djorovic) during the early 90s. It took time before Red Star was able to recover from this dranage of talent. At that time, Partizan had a very talented team (Nadj, Mijatovic, Ciric, Milosevic, Curcic) which filled that vacuum and became the dominant force in the Yugo-league.
I agree that Bjekovic is not very good. He is the son of the present director of FK Partizan, a great friend of Tumba. His father was also a player at the time of Dusan Bajevic. Like father, like son. That says it all. Petric, another Partizan boy, was an average player, but he had several very good seasons with Glasgow Rangers. Ciric, yet another product of Partizan school, is a different story. He was an awsome talent, but went to a great club (Barcelona) too early. There he had little playing time and stagnated. I think he is lost for football. What a shame. This is typical for a number of Yugoslav talented players who left country too early and joined famous clubs before they were fully developed. Almost all of them became failures. For example Ognjenovic (Real M.), Ciric (Barcelona), Lazetic (PSV), Marko Pantelic (PSG), Njegus (Atletico M.), Paunovic (Atletico M.), Djokaj (Majorca), even D. Stakovic (Lazio) and Vukomnaovic (Bordeaux). All these players would be much better if they stayed in the Yugo-league till they were 25 or at least 23. All of them left when they were practically teenagers.
Matijasevic came from Vojvodina. He was also standard player in the Yugo U-21 team. He was one of those who participated in the Vojvodina player strike. When he came to Greece, he was out of shape, playing no games for a couple of months. It was clear that he would be a disaster. However, I think he is a very good player and that he did a good job signing for Red Star last week. There, he will have a good coach and a plenty of time to get back to his game.
