ASM is messi like on his day, but consistency is an issue here. Anyone buying ASM for that much would be taking a huge gamble on his fitness. I don't see why you'd think ASM has proven himself significantly more of an asset than Willock that we'd demand 3 players from Arsenal including Willock. Willock has been in the team 5 minutes and he's already outscored ASM from CM. True he's not not assisting as much, but still, he's had less time to make impact.
