both teams have different reasons to win:
fenerbahçe needs to win to closely follow galatasaray and stay in the title race. for mourinho, a derby victory (after losing 3-1 to galatasaray at home) would increase the fans' trust in him. derbies are always important because they offer a chance to gain a big psychological advantage.
on the beşiktaş side, this season started with big dreams, but now we see those dreams fading one by one. they need to stop this bad streak and their inability to win. even a draw would relieve both the fans and the team.
my prediction is that fenerbahçe will win this match. i hope beşiktaş wins, but this is my guess.
In early rounds, Besiktas was at the top and looking strong contender for title, but their worst performance now brings them on sixth spot with 10 points difference from second spotted Fenerbahçe which is currently best team in Super League due to their improved quality and consistency most chances we will be having another win for the visitors in this game.
