Undiano Mallenco hasn't refereed many games in La Liga this season due to his international commitments (e.g. Costa Rica v Uruguay World Cup qualifier), but he was put in charge of the big derby game between Barcelona and Real Madrid this Saturday. couple of controversial decisions, a dubious offside for Henry as he advanced on goal and a more than possible penalty on Cristian Ronaldo by Piqué, but he got it right with Ibrahimovic's goal (he was just onside), and there was no question about the sending off of Busquets. One of Spain's more level-headed referees, expect to see Undiano in the World Cup. (01.12.09)
