Argentina captain Juan Manuel Leguizamon insists the Pumas will enter Saturday's QBE International against England with a united squad.
Leguizamon denies there is a rift in the camp that resulted in the resignation of coach Santiago Phelan, who objected to information being leaked to the media. Daniel Hourcade has been appointed as his successor.
Argentina finished bottom of the Rugby Championship and have lost star players Juan Martin Fernandez Lobbe and Juan Martin Hernandez to the treatment room, but Leguizamon has promised they will be ready for their Twickenham appointment.
"The team is very tight and our objectives are clear. People are talking about that, but we don't care," he said.
"Sometimes you have new coaches and you have to adapt yourself to the situation.
"We are all professional players and we must adapt ourselves as quickly as possible to the new system.
"There aren't many changes, so that makes things easier for the team."
Leguizamon has been skipper for the tour of Europe in the absence of Lobbe, who has been ruled out of all three games with an elbow problem.
"I'm very proud. It's a big thing for me to be captain for this tour," he said.
"Being captain of my country is something is very big, but now we are focused on the job we have to do.
"We are playing one of the best teams in the world. We have to be ready for that."
