I don't think you can say he failed at the 2012 Olympics. The route in which Turkey qualified, through the Euro qualifier was about as tough of a road as possible for them and they were able to succeed in qualifying. All of their losses came against higher ranked, and quite frankly better teams. I also think it's unfair for the coach to solely be the object of blame. Neslihan played very poorly at times and I doubt you would blame her for the failure.
Turkey will continue to do well regardless of who their next coach is because the strength of their domestic league. It will definitely be an interesting change. Who are the top candidates to replace Motta?
Actually i didn't say he failed in general, what i said is that he failed at the most important tournament, 2012 Olympics. During the tournament Neslihan's performance was poor, not even close to her general performance and it might be valid for many players in the squad showing bad performances at times as well. I agree about that. But my point is Motta was the coach and that makes him first responsible for everything in my consideration. Statistics, rankings etc. don't say everything. Turkey had enough potential to go far for many people including me but simply didn't manage to qualify. Anyway, i still feel pain whenever i remember that tournament. All i can say Motta gave SOS at that tournament and caused comprising question marks in our minds. Because of that continuing without him was an expected decision.
As already mentioned in this topic, Guidetti and Barbolini are the main candidates for this job. I don't have idea which one is better for the team but i just can't imagine Turkish NT leading by Guidetti would compete against German NT at the next EC in Germany. I think it is impossible for now to see Gui as the Turkey NT coach.
