The emblem I agree is part of our identity, but a small part. Our coaches, players, presidents are all part of our identity. Things change, and the club changes. The Delle Alpi was part of our identity, but we got a new better stadium.
Of course there are certain things that should never change: our name, our Italian core, being Torino based, winning above everything else - but we can't expect to never change anything. If we never change, we will become obsolete.
You mentioned the stadium. It's a good example. The new stadium is an improvement over the last one, but it kept its structure - it's still a football stadium. It's not something unseen in the world of football like this. It's like a new logo, with some modifications on the emblem, but still a football logo. Not the full negation of the whole.
You don't have to completely negate tradition to become markeatable. As I said, a football brand is different from general brands and should be treated as such.
If - and a big if - this helps the club somehow towards marketing abroad, it could be at the cost of the club losing a bit of appeal among their own established fans in Italy. It's heartbreaking, to be honest. Modernizing the club should be done while preserving its identity.
To me, this is an important modification with something that matters a lot to millions of fans, all for the possibity of maybe improving the merchandising a bit. Big risk - low reward.
If we are real about commercial revenue, start retaining big names like Pogba, improving performance on Europe and working towards a better league. This branding move doesn't move the needle, while it may hurt a lot of people who already support the club.
