@BrainOfLevy I really think you are over doing it in an attempt to defend him.
Internet debate 101 - eventually people polarise and argue extremes to make their point. Although, at this time, the point is essentially lost.
Sissoko hasnt been anywhere near as good as you are arguing. With the best will in the world he just hasnt.
Is he getting better? Yes. Is he actually any good? Well, no, but maybe he will be soon.
His base performance is that low he has moved from "utter turd" to "not a liability".
Not "Decent" to "Really contributing".
Only a few games ago his team mates were passing around him rather than too him, it speaks volumes
I have no agenda against him. I certainly hope he continues to improve and really impacts upon this season well, but its wishful thinking at best to suggest he has been any good so far.
