In the PL, Cesc has 80 assists, 35 goals in 212 appearances.
In La Liga, Xavi has 49 assists, 38 goals in 380 appearances.

I came across these stats and thought they were interesting. I suppose Fabregas tends to play a more advanced role perhaps, at least these days.

Also, Fabregas is 3rd in the all time Prem assist chart, 4 behind Lampard and 17 behind Giggs, so if he stays for another season or two he could easily overhaul them to go top.
