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
Norwegian official Tom Henning Ovrebo turned down several strong appeals for Chelsea penalties during the tie at Stamford Bridge.
Hiddink believes the time has come to hand critical decisions to a video referee and insists had one been in place this week, his side would be celebrating their place in the Rome final on May 27.
''In other sports like rugby and American football they have the ability to use technology at vital moments,'' he said.
''Everyone wait five seconds for the video referee before making a decision.
''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.''
Ovrebo's performance incensed Didier Drogba, who confronted the Norwegian official at full time and launched a foul-mouthed rant in front of TV cameras.
UEFA are investigating the embarrassing scenes and Hiddink must decide whether to play Drogba in tomorrow's Barclays Premier League clash with Arsenal.
The Ivory Coast striker is suffering with an ankle injury and may also be carrying some emotional baggage, but Hiddink will not let his antics on Wednesday cloud his overall opinion of him.
''Didier has been playing very well. From the moment we started working together he worked hard in training,'' he said.
''He had a good influence on the team and was very efficient.
''I can be very satisfied with his performances but neither of us are happy with the way he over-reacted after the game.
''Before that happened he was perfect - he has been easy to work with. We had no problems or arguments, big or small.''
Raising morale in time to face Arsenal is Hiddink's most pressing challenge yet the Gunners are also reeling from their own European heartache.
Manchester United left little doubt in an easy victory at the Emirates Stadium that Arsene Wenger must strengthen this summer if the north London club is to compete for silverware.
Hiddink believes they need up to three new players who will add ''power''.
''They will analyse their situation and might come to the conclusion that, with respect for the style that they play which is nice to see, maybe they need one, two or three players who can give even more power to the team,'' he said.
''If they want silverware I have that conclusion, but it's not up to me.
''They're not winning anything but they're intelligent enough to make this conclusion.''
