Nope won't happen, just because they bought two stars doesn't mean instant success ahead of Barcelona, Real Madrid, Manchester United and Bayern Munich. A possible underdog is Borussia Dortmund. Galatasaray doesn't have that spark that will get them to the finals.
First in Süper Lig, bought Sneijder and Drogba. Other decent players. Galatasaray winner of CL 2012/2013?? What are your thoughts?
