Extra officials are working, says Collina

The UEFA experiment has been derided by naive journalists in the mainstream press, but Collina believes that it has been a good innovation.

At the Leaders in Football conference he said: “It gave positive feedback in terms of better (match)control.

“It’s a good deterrent. The number of pulls and pushes in set pieces have decreased, probably because of the presence of the extra referee. We had no controversy because of their presence.”
