Manchester City have completed the signing of CSKA Moscow's highly-rated Brazilian striker Jo on a four-year contract for a fee believed to be in the region of £19million.
The 21-year-old found the net 44 times in 77 games for the Russian side following his transfer from Brazilian side Corinthians in 2005.
City manager Mark Hughes said of his first signing since replacing Sven-Goran Eriksson as manager at Eastlands: "He's a big talent and a young man with a big future.
"A lot has been said about him and there was a big expectation on him coming out of Brazil. So with the success he's had I think it's a real coup that we've been able to bring him to the club.
"He's a big guy, in stature and in ability, so I think everybody will enjoy watching him play."
Jo had earlier said of his decision to leave CSKA: "There is a hard moment for every player - when you have to leave a club which is dear to you.
"CSKA is nothing less than a large family. I spent two exciting years at CSKA. During this time I kept improving myself and my name became known in Europe.
"I enjoyed working with all of my team-mates, and together we've won many remarkable trophies.
"I will always keep in my memory the days at CSKA and I wish great success to my former club."
