Expected managers. I am just a little bit surprised to see Van Gaal that high.
Lol Real Madrid 8 to 17 :D Porto with the Portuguse League and Cup I guess. 29 looks pretty amazing. Barcelona 21 to 21; this just shows that Real Madrid was too good for any team before 2004-2005

I found it a bit injustice to see Mancini is that high, those trophies after Moggi's scandals in Series A counted right???

As for the club, it's quite emberrasing for Arsenal to be that low considering their fame... (stat wise)

@Emre

Yeah, Madrid had a bunch of blank seasons where we won absolutely nothing. Disappointing, but that's our history now. :P
