I can't see the other team so I can't tell you if there is a colour clash.Possible colour clash ?
And that looks like a game with paying spectators too so a supply league level maybe, even if dev squad.
According to the Competition Rules under which I operate it is the home sides responsibility to change in the event of a clash of colours. I am sure many members operate under the same guidance in the event of a colour clash
It's the away team in my leagues. Still doesn't stop them turning up in the same colour despite it never being the first time they've played each other or the fact the colours are all in the league handbooks
Does it then take a referee to say, no, not today lads, if you have both only got that strip then am deeming it a clash?
if you always do what you have always done, then you will always get what you have always got....
If it was the done thing to play the game, spirit of the game and all that, in the picture shown for example, I would serious wear my blue Adidas top, just to prove my point, I would be like "well if its ok for you both to clash then I might as well blend in too"
