There is obviously a risk, even more so for me with players whose main attributes is dribbling as I tend to find if they cant replicate what they have been doing when its time to step up, their game is more likely to fail... hard to tell how big an issue it could be until he is here and you see what his mentality is like..
I have come round to him a lot more in the last few weeks watching the footage out there... his game is a lot more well rounded than I thought, good vision/passing range.. my other concern regarding end product, he looks to have improved this season on that as well.
Still don't think its worth the crazy money being mention (90-100m) but looks like it is in a more reasonable range now and I also reckon he will be another one that might take some time to settle but if it 'clicks' for him, we will have some player on our hand.
Ultimately agree with Dula too, Arteta/Edu have generally been great with quality of signing and more importantly what the team actually needs.
