By any criteria, Hollie Davidson must currently rank as one of the three or four best referees in the game, with power to add, and it comes as no surprise she will be making her Six Nations debut in February when Ireland take on Italy.

Davidson is here to stay and, at just 33, hers could be a long career at the top.
Watching her recently in a variety of club and international games, three things impressed me above all others in her modus operandi.
Firstly, she is completely in charge of the TMO process, which puts her ahead of most refs.
Computer-like neutrality
She only uses it when needed...
