To be fair Konya is one of the worst teams in the league now, and we beat them 3-0 last week and we are notoriously not great at scoring, and we didn't even have Icardi, so its not that hard to beat Konya. However, in any case, scoring 7 goals against any team in the league, even if it was Istanbulspor, it is a great success, and certainly a team like Konya who is famous for their defensive system. I think Fenerbahce is great at scoring, I do not know what makes them so great at scoring, but they are just unreal at it, I wouldn't really consider their defense good, I find our defensive four a lot better, but their attacking is just unreal, another great ton of scoring by them. Its still neck and neck, its going to be quite tough for the entire season to be like this, its getting nervewrecking.
Actually, Konyaspor is not that bad of a team, they just have bad luck in the fixtures. Last week they played against Galatasaray and right after that they played against Fenerbahçe. It is not easy to play with two big clubs consecutively. As you said, Fenerbahçe's offensive line is really good and they can score goals very easily. The defensive line is not that bad, but the absence of injured players puts Fenerbahçe in a difficult situation in terms of defense.
The Bonucci transfer will close this gap in defense and Fenerbahçe will continue on its way in a stronger way.
Meanwhile, Fenerbahçe won 19 times in the 19 matches played by Fred. An excellent statistic.
