There have been similar looking playing surfaces in German Bundesliga, European cup competitions and other supposedly top leagues. Weather conditions in Manaus are far from ideal and even teams like Bayern Munich had problems for a long time to get the playing surface into perfect shape because the new arenas & their roof constructions in general are anything but perfect when it comes to lighting and stuff which is critical in that regard.
Besides that it's a bad joke that they even play in Manaus, there won't even be a 2nd division team in that city after the world cup, so basically they spent a shitload of money to build a stadium for 4(?) games...
All that being said, it's a joke that the stadium in SP isn't 100% done and several other stadiums are in similar shape. Especially if you take into account, that they build this one for the WC when there already was one of the most modern stadiums (Morumbi) in all of Brazil available. Even just updating/modernizing Morumbi probably would have been cheaper and needed less time.
