Well yes, but as you say they've been doing that for years. I wouldn't worry about them working us or De Zerbi out in the future, when the template to deal with us is already there.
Isn't Veira's main problem that their key player last season actually belonged to Chelsea?
Whereas our team's been purring and getting results for months now, and the effective way to play against us hasn't really changed for the last 3 years.
