Di Natale has a stunning 7/8 in Form as well, so he should be green and orange on a regular basis.
Anyway, I have not yet seen Barcelona, Real Madrid or any Manchester club selling all their star players and replacing them with rubbish. In three transfer windows, the only high profile transfer I've noticed is Ibrahimovich's move from Milan to Arsenal.
Some high 70's and low 80's players also switched clubs, but no real shift in power between clubs yet.
I wouldn't call Ibra's move to Arsenal realistic, but I wouldn't call it unrealistic in a game such as this either. Arsenal being mid table for the 2nd season in a row needed to pack some more punch to get points, and Ibra is a goal getter.
I'm a bit annoyed at always starting in a Dutch crap team though, I liked the 2011 solution where you could inspect and choose between low-lower mid range clubs from several countries.
But in all fairness, I personally forwarded the idea to start off in a less reputed country to hone your skills and to get a natural difficulty increase by moving to harder leagues, rather than the game just increasing the game speed as your player got better, as pes 2009,10 and 11 did to keep the game somewhat "difficult".
