Chelsea boss Guus Hiddink wants goal line technology introduced after being denied a goal in last night's 2-2 draw with Juventus.
The result was enough for Chelsea to progress to the Champions League quarterfinals, though Didier Drogba had a goal disallowed.
Drogba's free-kick looked well over the goal-line before Gianluigi Buffon clawed it back but referee Alberto Undiano waved play-on.
Hiddink, though, called for the introduction of technology to finally solve such controversies.
"Technology must be used on this," he added. "Then there won't be a dispute, yes or no.
"We did it in my very early days at PSV in the 1980s and it worked out really well. But the people who were deciding didn't want to know, and that was 20 years ago.
"Now I think the technology is so perfect that, for me, it must be done.
"I'm happy and satisfied with the reaction of the team. Whether it was a justified decision, yes or no - the referee has his problems to see whether it was a goal, and we should help him with that, but the team reacted very well."
