Giggs says while there's concerns at the back, United' scoring power is exciting.
He told Absolute Radio: "Yeah, I think at the moment it's a case of the team scoring more goals than the opposition. We've not had too many clean sheets which everyone wants but to be fair, like I said, you can't complain where we are at the moment. We are top of the league, a bit of daylight in between us and City so we can't complain but yeah, we'd probably like a lot more clean sheets.
"We've got so many options up front obviously with the addition of Robin who's brought that bit of class to the centre forward position already with the class of Rooney, Chicharito and Welbeck and obviously Kagawa started season, he's been injured as well, we've got so many options and so many different variations that the manager can play up front."
