BBC has reported that Man City are still in the race to get Ronaldinho.
Manchester City executive chairman Garry Cook remains confident they can convince Brazilian star Ronaldinho to sign for the club.
Ronaldinho, who struggled with form and fitness problems last season, has also been linked with a move to AC Milan and Chelsea, but Cook said City are genuine contenders in the race to capture one of the game's biggest names.
Brazilian striker Jo joined Manchester City from CSKA Moscow on Wednesday for what the English Premier League side said was a "club record" undisclosed fee.
The 21-year-old forward, capped once by Brazil, signed a four-year contract and in the process became Mark Hughes's first major signing at Eastlands since he replaced Sven-Goran Eriksson as City manager.
Jo, full name Joao Alves de Assis Silva, is a left-footed forward who joined several fellow Brazilians at CSKA in 2006 when he moved from Corinthians.
It had been reported that City expected to pay around 19 million pounds (38 million dollars) for the striker, who scored 44 goals in 77 matches for the Russian club.The club are keen to pair him with the former World Player of the Year.
