The best site IMO. f***ers even speculate kits based on what they hear or see s*** leaks and then do some photoshopping to recreate.
One of the better sites around, aye. Don't quite like their eagerness to impress with kit drafts though as some of the details might not be accurate while they have been known to steal photos from other sites too.
Footballkitnews.com is another good site too. It's a bit slower recently but the updates last seasons were fast. They also have an upcoming kit releases section for release dates.
