As said previously good to see FIFA focusisng on the important things.
With regards to the comments about the tight shirts, even as a ref, I wear SKINS underneath my uniform as compression garments - I have short sleeved top, shorts and the "sox". They make for much more comfortable refereeing and be it psychological or otherwise I feel they do make an impact in terms of less lactic acid effects after matches. Considering us not so high up the ladder refs can do between 2 to 3 full games Saturday and then the same on Sunday, they do make a difference.
