This thread is retarded. This quite simple, there is no change. Replica jerseys have a thinner collar as they don't use the same Fly Wire technology as the on-field jerseys. The picture at the start of this thread is of a replica jersey, identical to those sold last year. There no change to the current on-field jerseys.
Also - why is this important?
Also - what's the average age of this thread? 13, 14?
