Edin Dzeko has bid an emotional farewell to Manchester City fans after joining Roma on a season-long loan and said he will always keep the Premier League club close to his heart. The Bosnian striker, who joined City in January 2011, has been loaned with a view to a permanent transfer to the Serie A club 'if certain conditions are met'. 'After four-and-a-half years, filled with your chants for me and my love for you, the time has come to say goodbye,' the 29-year-old said in a letter, posted on his official Twitter handle. 'I have spent some of the best moments of my career at Manchester City, moments that I will never forget. 'Thank you for everything.' A crowd favourite at City, Dzeko, scored 72 goals in 117 starts and won five trophies for the club but struggled to break into the starting line-up last season. 'I will continue to be a big fan of Manchester City, to whom I wish all the best and many more trophies and happiness in the future.' he added.
