Republic of Ireland manager Mick McCarthy has played down fears that Saturday's European Championship qualifying match against Russia may be postponed because of heavy smog in Moscow.
The eastern side of Moscow - where the game is due to be played - is troubled by smoke from out-of-control forest and peat bog fires.
Both the city's airports were closed this morning and locals had to wear protective masks.
The squad trained in the Dynamo Stadium tonight and McCarthy said: "It has been beautiful. It was a bit misty when we flew in but we have had no problems."
McCarthy reported a clean bill of health among his squad, with everyone taking part in training.
Although Ireland are top seeds in Group 10, this promises to be their toughest match in the group. But McCarthy has every faith in his players and said they had come to win, even if a draw would be a good result.
"I was sitting having a coffee with someone and they said: 'This is a tough game for you'," said McCarthy. "But I bet the Russian coach has been sitting somewhere considering the fact that Ireland is a tough game for him.
"It is good when people expect us to win because it means we have good players. That is better than people expecting us to get beaten as obviously that would mean our players weren't so good."
When asked if Roy Keane's absence put extra pressure on him, McCarthy said: "Of course it does, and that is going to be there all the time.
"The more people give it legs, the more it is going to run and run - it is an unfortunate fact of life.
"I don't know when it is going to end. It probably will still be going on when I have lost my teeth and my eyesight and all my hair has gone. I'll be sitting drinking my pint and someone will say: 'There's that bloke who sent Roy Keane home from the World Cup'.
"I am on record as saying that when Roy played for us in the World Cup qualifying campaign we were a better team, and we all wanted him to play. But it is an unfortunate fact of life that it is not going to happen.
"Roy was going to retire after the World Cup anyway, but he has chosen not to.
"There is a suggestion he may have played if I wasn't here, but I can't do anything about that, and if that adds a little bit more pressure to me then so be it.
"Whatever happens, it is still results-based. If Roy was playing and we lost here or didn't qualify, it is still the same. If because he isn't playing and we don't get the right results then people want to scream from the rooftops that he should be coming back, I can't do a thing about it.
"It is a very sad situation that one of the world's greatest players is not playing for his country, but that is not my doing and I cannot do anything about it.
"If it adds a bit more pressure then bring it on, because I have lived with that pressure in the past before and it is not going to affect me any more - I shall keep trying to smile."
FAI officials said they have received no indications from their Russian counterparts that the match is under threat.
