I'm pretty chilled. Can't think of any Emery signings that haven't worked out yet barring Zaniolo (I'm being patient though, and it's a loan) and possibly Diaby (again, I'm sure he will come good and has contributed a lot already)
We're 2nd, with a large part of the team our previous manager couldn't motive/inspire/ manage (his shortcomings)
Unai has the mindset, skill set and knowledge to get the best out of his team and players. I've no doubt any player he signs will benefit from the same Coaching and techniques he employs.
If we are being cautious/ savvy, there will be a reasoning behind it and not due to lavk of ambition or funds (ffp for example) I'll wait and see where we are at come the end of the window and remain a believer in the project.
