Alexandre Pato completed his move to Corinthians on Thursday. The former AC Milan striker signed a four-year contract with the Sao Paulo club for just under $20 million. Instead of a signing-on fee, Pato, whose six years with Milan were blighted by a series of injuries, has secured 40 percent of any future sale.

"I wish to salute, but above all to thank, everyone,” the 23-year-old wrote in a letter published on the Milan Web site. “From the President to the many people I worked with in these unforgettable years at Milan. I am going to Brazil, to Corinthians, so I’ll have the opportunity to play consistently. It won’t, however, be easy to forget Milan. I am and always will be very tied to this jersey, the club colors and all the Rossoneri fans. Above all at this moment my thoughts and my biggest thanks go to them.”
