Referees to 12 May 2013
There are semifinals in England, Italy, France and the Celtic clubs who make up Pro D2. It's a time of ambition when intensity heightens.
It is a time when the gulf between winning and losing is gigantic, even if the points' difference is slight. It is a time for referees to be at the top of their game, their concentration absolute.
In South Africa the Vodacom Cup has reached semifinals and the two matches will be refereed by the Jonker brothers.
