Bad attitude and self interest over team spirit is what cost us. We didnt really lose our best players but probably our worse (apart from Karagounis). Katsouranis nothing special , Gekas good but nothing special. some Spyropouloi Tziolides nothing special. And thats the reason that we have high chances to make a comeback. Because we didn't lose the talent. Just the morality and consistency. BVB had a similar season, noone went crying and judging "we cant beat even Hoffenheim in our current form". Chelsea had a similar season, noone went "here come the dark days like before 2005 , we gonna lose to Nottingham forrest next season just because we can". We didnt really need a coach just someone to unite them. Besides you can't expect to teach ball to these players. Most of them already play under some of the best coaches and train against some of the best players , their teammates. All you gotta do is find a strategy or two that will suit your
