Brazil 10 and 19 are too . The only reason I am watching it is my Grandson and his Dad are there tonight. Maybe these Brazilions are feeling the cold lol
Referees have more need of gloves than the players ('cos they have to write things down, which is almost impossible with numb fingers).
I've actually realised that I'd have to abandon a match (played at -6C, with a wind chill down to about -15C) if I needed to caution someone, or send them off, because the whole of my lower arms were totally numb!
I keep a pair in my kitbag. Haven't used them yet, though I fear it won't be long.
In our defence, rugby referee's do have to give a lot more hand signals and complete more on-field writing than kissba...sorry, football refs.
