"Hamburg gave me an opportunity to have a look at some of the younger striker options that we have," Hughes told City's website. "It's important that they have the opportunity to play in these games in good stadiums, against good crowds and good opposition. That can only help their development, so it's important that I understand what options I have.
"It's still a number of weeks to the start of the Premier League, there's a lot of work to do but I was pleased they were able to get on the field and have an impact. I think for these young players that is really important."
