Jose Mourinho has called for referees to be allowed to use technology, citing Arjen Robben’s contentious penalty at the weekend.
The Netherlands international won his side a late penalty to secure a 2-1 win over Mexico in the Last 16 of the World Cup.
And the Chelsea boss has admitted that officials have a difficult job, which could only be helped by video technology.
“If you have technology, you have a chance to have a fourth official watching on the video,” he told Yahoo Sport.
“So I think the referee should also be happy to have the chance in case of doubt.
“The chance to clear every doubt and the chance to make the right decision, because when one country feels that one bad decision influences its future in the competition, I think it's hard.
“And it's important for Coaches, for players but also for referees.
“I think technology is something the referees would welcome.
“Arjem was my player and I know better than many what a fantastic player he is.
“I also know that because of his speed and because of his creativity he is punished a lot with fouls by opponents who cannot stop him.
“I also know that sometimes he tries to get an advantage and he tries to get a free-kick or he tries to get a penalty.
“I think it's important for the players to help the referees by being honest on the pitch, to try to win the right way.
“But the reality is that not every player behaves that way and referees have a difficult job.”
