Another question in Spanish for Gianni Infantino.

Gianni Infantino adds that Fifa has tried to do its best and they hope to have some good news.

Gianni Infantino says it's not easy when you have 300,000 accredited people from outside the US and you have to check them.

He adds the world is an "aggressive world" and you have to "check everything".

BBC Sport's Dan Roan is up next. He's asking about freedom of movement and how welcoming this World Cup is.

The first two questions for Gianni Infantino are in Spanish, and unfortunately, I cannot speak Spanish.

We want to unite the world. If I can ask you one thing, again, if you want to criticise me, it's fine. But promote the unity of the World Cup, promote people coming to the World Cup, feeling those emotions that all of you have been feeling when you were children. I hope you can still feel them now because we want to unite the world.

The floor is now open for journalists to ask questions...

Let me just say that our entry price, which is 60 dollars, is the lowest entry price of any of the American sports in the play-off phases, our average price which is below 500 dollars is again the lowest of the American sports on average.

It is unfortunate what happened to the referee from Somalia. Again, we don't control everything. We try, we will discuss, we will speak, we will see. Sometimes it's good to chill, relax, we work on everything, we try to solve everything. Sometimes to immediately start screaming and shouting has the opposite effect of finding a solution.

Believe me when I tell you, we always try to find solutions. But we need to respect we are not the kings of the world who can rule over governments and police forces. We are a sports organisation.

Gianni Infantino is now talking about the third topic he mentioned, visas.

He asks the journalists to "promote the unity of the World Cup".

Gianni Infantino says it is "unfortunate about what happened to the referee from Somalia" but Fifa "doesn't control it".

He adds that they always try to find solutions but they are "not the kings of the world".

"Who is investing in South Sudan? Nobody. We do it," says Gianni Infantino in reference to where investment from revenue goes.

The second topic is tickets - ticket prices, and are stadiums going to be full or not?

We sold until today over 6 million tickets, there are always tickets on sale as you know, we need always to keep some tickets for those teams who qualify for the additional rounds.

The demand has been unprecedented but not unprecedented by a little bit, but unprecedented by a factor of ten or more, the number of ticket requests we have received has been absolutely incredible.

He says that if Fifa sold their TV rights for the games, then they would make more revenue so they have to "strike a balance".

Gianni Infantino says they have sold 800,000 tickets for the games in California and Los Angeles. Only three people who purchased these tickets complained, he says.

Let me say that on Iran, I am very happy because I went to see the Iranian team in Turkey in March this year.

People were saying Iran couldn't come to the World Cup, I promised them they will come and if I have to go on a bus to Tehran and drive them here I will do that. Their answer was we will take the bus and drive ourselves if needs be. We qualified and we want to play. This is the spirit of football. There are challenges, it's not easy, but I don't know who else would have been able to ensure in these circumstances - which we could not influence - Iran could come and play. When Iran plays, the stadium will be full and I hope there will be a positive atmosphere because this is football, it's about people forgetting their realities and focusing on a match and a team.

I am very happy we managed to get Iran to come and play. I am proud of the work of my team.

Gianni Infantino says the entry price of 60 dollars is the lowest of any American sport and the average price is 500 dollars.

He compares it to American sport and how the tickets for the World Cup are accurate.

The three topics coming up all the time in the last few weeks - Iran, tickets and visas. Nothing to do with football, a lot to do with the current situation with our host countries, with the world and the way it is.

Now we're on to the topic of tickets and Gianni Infantino says they have sold 6.5 million of them up to now.

He goes on to thank the fans who have bought tickets or are buying tickets to come to the World Cup.
