Tevez was reportedly bought by Corinthians for between US$15 to 20 million but not paid by them but by another third party. Sounds like Abrahamovic is behind this where he will play in Brazil (get this, an Argentine bought by a Brazillian club - must be a first) fo 2-3 years and then this "third party" will share the profit from the proceeds of future sales with the club or something like that.
I think Chelski's owner is behind this and he will bring him to Chelski after 1 season.
