Recent home kits have been better and this early, probably bogus, mockup is on the right track. But we have to get rid of the green/white crap for the second kit. An all white will do. As for the third, I'd like to see blue but if blue is too dark for a third kit (never go light blue, of course) I wouldn't mind something ahistorical such as an all yellow kit.
Those purported kits for next season look quite alright actually. I do like the fact the away kit has the proper coloured badge, rather than one faded to blend in with the main colours of the shirt.
Would be quite happy with those.
