New FIFA president Gianni Infantino believes video technology in football is "inevitable" and would be happy for the English and Scottish Football Associations to trial it.
The 45-year-old is in Cardiff for the International Football Association Board AGM where it is expected to give the go-ahead for live video trials.
The trials, which will need two years of testing, will be designed to help referees make game-changing decisions relating to goals, penalties, red cards and mistaken identities.
The English and Scottish FAs are keen to trial it, with English FA chief executive Martin Glenn hinting it could possibly happen in next season's FA Cup, and Infantino would be open to allowing the home nations to be guinea pigs.
"I will hope we see trials in as many places as possible in the world but also in England and Scotland," he said.
"I would like everyone to have an open mind about these things without prejudging what the results at the end will be. The recommendation is that this moves forward. We have to discuss it tomorrow.
"Sooner or later it will be inevitable. Let's start to do something sooner rather than later."
Also on the agenda on Saturday is sin-bins and the possibility of allowing a fourth substitute in extra time in cup competitions.
But video technology could send football into a new era and Infantino knows the IFAB must get it right before anything is given the official green light.
He said: "Technology is on the agenda, the experiments to be done are on the agenda and it's important to protect the traditions.
"Football is such a successful sport because some wise people have protected the history but we cannot close our eyes to progress.
"We have to look forward. Look into it, test it, maybe it's successful, maybe it's not. Maybe we have to fine-tune it and maybe it takes a few more years to reach the right solution.
"Football has a particularity which is the flow of the game and we have to see what impact technology has.
"We are confident we can come out with something good at some stage. I am not afraid of anything. We have to acknowledge we are in 2016 and we have to be open."
