I was thinking about this. There is no United player advertised in the ad if I'm correct ? What a huge win that would be for them. I quite like this turning a transfer saga into a marketing campaign tbh. It's cool as long as you're not at the losing end of it I.e your player leaving.
Toward the end of the long ad, you can see the shirt under his sweater. It's not a jersey. It's some white shirt with a black pattern. Doesn't look like Juve apparel though, just some generic T-shirt.
