Ed is a strong player and would be 1st choice striker in all but about 3 or perhaps 4 teams in all of Europe. But he is at Man City and for the moment, whilst it is clear that he is being given a run of games, because Kun is out, and that run is showing what he is capable of, when Kun comes back, Ed will go back to being 3rd choice striker, along with Jovetic (if he ever gets fit again!). And given the wealth of games that are on the table this season and hopefully in seasons to come, in all four competitions, Ed will always be needed for exactly the reason he is playing right now.
I like Ed - He could have scored 4 or 5 yesterday and was clearly enjoying his time on the pitch. As long as he is happy to carry on accepting that he is and will be 3rd choice, there is not anyone else I would rather have
