Manchester City defender Aleksandar Kolarov signed a three-year deal with Serie A club Roma, the Premier League side said on Saturday. British media reported a transfer fee of 4.5 million pounds ($5.85 million). The 31-year-old won two Premier League titles, an FA Cup and two League Cups in seven years with City. 'When I came in 2010, honestly, I didn't expect to play so long,' the Serbia fullback, who joined City from Roma's rivals Lazio in 2010, told City's website. 'Today is the day I have to say goodbye. For me, it's a very sad day. I am proud that I was part of making City the club that it is.' On joining Roma, he added: 'I am extremely happy to be here,' he said. 'I will give 100 percent and more for Roma. My objective is always the same -- to win.'
