Actually not really. They lost playoffs to LATVIA in 04 and then to Swiss in 06. And at the moment this Bosnian team is very good with 3-4 real top class players who are having mvp seasons in Bundesliga.
Turkey as qualified for how many World Cups in history 2 maybe? So really not a surprise.
2002 is a long way for that one most players are not there anymore Sukur Ilhan Korkmaz Basturk Sas Umit Akyel Tugay Alpay etc. And remeber in last Euro both Czechs and Croats choked late in games if not the Turks would have been out group stage first and then in 1/4...The thing is Bosnia is very strong that's why combining with Turkey's history in WC won't be a surprise.
