Evra has slammed reports claiming Gallas is furious at missing out on the captaincy.
"That is bull. It's not true," said the Manchester United defender.
"The mood is good. William is a professional and he wants to play at the World Cup. Everything is okay. I guarantee the atmosphere is very good. It's not a problem. To captain the team at the World Cup is an honour. I'm very proud.
"I thanked my team-mates, because they're happy I am captain."
