The VAR was introduced to reduce controversies, and instead, they have increased - possibly because we Italians like to stoke them.
We've all had meetings with the referees. We're all clear with how VAR works, and ultimately, you want the rules to be fair.
The feeling is that video assistant referees and technology are here to help us, especially for justice in the penalty area.
Clearly, I'm for the VAR.
I think retrospective viewing of diving is nearly more important than some of the technology they are on about bringing in. If you do that and players get banned, it wouldn't take long before you'd cut it out.
There are challenges in terms of the measurement of VAR for what are known as nonlinear derivatives, where things like gamma and vega are important dimensions of the risk.
Everyone talks about VAR, which is great. It will help the referees no end. But if you've got VAR in place and VAR becomes the ref, I'm not sure that's good for the game.
Obviously you have to trust the VAR to make the right decision.
If we want football to be a sport that is no longer a sport, then use VAR on every incident. However, if we get to March, where every point becomes decisive, then games can last three or four hours.
If I sit here and say I don't agree with VAR, I'd be lying.
VAR can remove injustices, but decisions need to be taken faster.
Brazil versus Argentina is always a great game, with great football and scoring chances.
Football is always a very emotional game, and VAR is changing that a bit.
One important measurement issue concerns the fat tails problem that I mentioned earlier. VAR is concerned with extreme outcomes. If the tails of the probability distributions we are using are too thin, our VAR measures are likely to be too low.
With VAR, the refereeing errors will be reduced, and therefore, we'll all be on equal terms. It will take a lot of the responsibility from the referees on vital decisions, like penalties and goals, and they will make far fewer mistakes.
I always said that VAR is a very important tool on objective and important decisions.
I think VAR is a very healthy development within the industry.
I have always said that I am a friend of VAR.
