Arsenal also played in an Ajax type kit pretty recently with weird navy bits on it too. Liverpool played in a kit with diagonal orange stripes/flashes. United played in a red and black fading kit, City whacked a maroon collar in and centralised the badges. Clubs tweak things, it happens everywhere and it’s nothing to do with destroying tradition. Such melodramatic nonsense.
Clubs like to mix it up and it makes commercial sense. If you churn out the same design every single year then you see more sales drop off because people who are in the target markets go ‘looks just like the one I have already, I’ll just wear this instead’.
If it looks good in person/on pitch and we play well in it, then it’ll sell. That’s how it goes.
