Galatasaray WAS good enough to be champions but this year they look like they have absolutely no way of playing, they have some problems with their tactic, they are having it hard time to score, they are having hard time creating goals for themselves, and their defense seems a lot slower, how can the same people could end up being slower? I have no idea how that happens but as I can see from the situation, the yare much slower, and when the defense of a team is beast one season and terrible another season (which rarely happens) and they have hard time scoring, that means they are going to lose more often.
I believe that Galatasaray got too confident and just stopped training too hard, they were hungry for a title, they got two, now they are relaxing and just cruising, which is the main problem. That's the power of Pep Guardiola, he can keep a team hungry even after four titles, which isn't that common in many nations, you have to be miles better like PSG to keep winning.
Galatasaray this season is in bad condition so indeed we can't expect much to see them dominate the super league again, Galatasaray have been in pretty bad form so far and even they have just been knocked out of the Champions League this season after losing to youngboys 4-2 on aggregate, in the super lig they indeed still been able to maintain good form and so far have been able to win two consecutive victories over weak teams, but To be honest, although Galatasaray are in the top 4 of the Super League standings at the moment, I don't dare to hope if them can repeat what they did last season because other teams are also starting to improve their current squad, Fenerbache and Besiktas I think will be a consistent team to compete for the championship trophy this season.
