Chelsea boss Guus Hiddink has urged football's authorities to come to the aid of referees by introducing video technology for key decisions.

Hiddink has struggled to accept the Blues' Champions League exit in the wake of Wednesday night's controversial 1-1 semi-final draw with Barcelona when Norwegian official Tom Henning Ovrebo turned down several strong appeals for Chelsea penalties.

Hiddink believes the time has come to hand critical decisions to a video referee, insisting; "In other sports like rugby and American football they have the ability to use technology at vital moments. Everyone waits five seconds for the video referee before making a decision."

He added: "It can be done only on key moments that make a difference to the outcome of the game otherwise it would stop the game too much.

"The video referee must have authority to overrule the first man in charge.

"In rugby and American football when the video decision is made, that's the decision.

"It's a fact that if technology had been in use we would be in the Champions League final now.

"It would help a lot what is a difficult job for the referee when they have to make crucial decisions. It's up to UEFA whether they act."
