Fenerbahçe and Galatasaray are making excellent transfers and appear likely to continue doing so. Beşiktaş has no chance of competing in such an environment. In my opinion, they should not spend any money on transfers and should wait for seasons when Galatasaray and Fenerbahçe are in worse financial and administrative shape. Beşiktaş will not be able to compete with these two clubs in the new season...
I don't remember any players Fenerbahçe has transferred so far. However, I think they will focus more on transfers this term. Because they lost the championship to Galatasaray last year, and the year before that was the same. They don't want to lose the championship to Galatasaray this year, but Galatasaray is seriously increasing the gap by transferring great players.
