Hello,
I have a shirt that has been said to be game worn and has Ronaldo on the back in large lettering and the number.
It also have the seria a badge on the right sleve.
As far as I can tell, everything seems to be good about it.
There are a few bobbles on the shirt and the size and label on the botton of the shirt has been removed.
If anybody has any better information about how I can tell whther this is a amtch worn shirt, I would be very gratefull.
