Fabregas carried your team for a good few years, highly doubt you would have continued qualifying for Europe had he not been there to inspire and lead your squad, especially after the whole Eduardo-Gallas stuff. That said, there's no way to tell how you would have done in that situation with/without him so there's no point denying it.
The very fact you're ranking Cygan as a better player for Arsenal than Fabregas, who now plays for one of your main rivals, is the very definition on salty though.
