I agree completely, and I've been saying it for ages.
People need to get realistic. Football is just another job. Would many people reject a better paid job if they had the offer? Hell no, everybody wants as much money as possible for as little work as possible, its only natural.
Critisizing a player for choosing another club which doubled his salary is ridiculous. Piazon doesnt owe anything to Juve, he's free to choose the club he wants.
And let's face, it we're not that attractive anymore. Fact is, we're nowhere near the first tier of European football anymore, We were once in the top 3, now we're not even in the top 10. Thats the sad truth. If I were in Pizaon's place, even with the same salary offer I'd still choose Chelsea.
