I think this is a good move for Danny, and I wish him well in the future.
City are bringing in world class strikers left and right, Danny would have been about number 6 in the pecking order. For him to be first team (presuming we sign them all), 3 players would have had to be injured. Chelsea is a Champions League club, a contender for the league/cups and is a fashionable part of the world. If any strikers at all get injured, Danny is in. Who else is there? Di Santo?
There is a high possibility that Daniel Sturridge will play more Champions League games in the next two years than Eto'o and Tevez put together. For a young lad with the talent he has, it would not be a massive shock if he gets in the England team after the World Cup. He wouldn't get anywhere near the minutes at City that he would at Chelsea.
He hasn't been a twat about things, he said he was leaving over 6 months ago and has stuck by it. It's not like he has any major affinity with City; we gave him his first Premiership start, but it isn't like he has been at the club since he was 8 or anything.
It's always disappointing for us to lose a player with such potential, but if Danny thinks this is the best move for him, then good luck to him. I hope we prove him wrong in the long run.
