Brazil striker Robinho ended his spell at Manchester City when he joined AC Milan, just two years after arriving in England for a British record fee.
Although financial details were not disclosed, it was the highest profile deal on a quiet final day of trading before the transfer window shut until January.
Robinho spent last season on loan with Santos in Brazil after an erratic first term with City.

European spending down
Gross transfer spending by top clubs in France, Germany, Italy and Spain was down 25 per cent to 40 per cent compared with 2009, widening the gap with their English peers.
Twenty-six-year-old Robinho, who cost City $50 million from Real Madrid and has played 80 times for his country, never settled in Manchester and spent six months on loan at Brazilian club Santos last season.
Milan hope Robinho, who has signed a four-year contract, will be a key element in helping the Rossoneri regain the Serie A title they last won in 2004.
"AC Milan annnounce the permanent signing of Robinho from Manchester City. The Brazilian player has signed a four-year contract," Milan said in a matter-of-fact statement.
