Only the big 4 European leagues would be stronger than it now. Young Brazilian players are now staying much longer than when they would usually leave in their teens. You’ve got the likes of Neymar, Ganso, Damiao, Lucas amongst others who still plying their trade in Brazil despite being on the radar of the big European clubs for some time.
Damiao is going to be a superb player wherever he goes, very much like Pato. They’re probably on par right now now. Pato has stagnated a little but I think that is more down to persistent injury than anything else.
I’d definitely be expecting Brazil to take home the WC in 2014 with home advantage, they do appoint some hopeless cases as managers though who have a habit of making inexplicable selection decisions.
