Sir Alex Ferguson has promised to use all his weapons in Manchester United's continuing battle with Real Madrid over Cristiano Ronaldo.
But this week has seen another war of words between Ferguson and Calderon, and the United boss said: "I don't care two monkeys about our relationship with Real Madrid to be honest with you.
"We have the player we want. They don't have the player they would like. All that is going on regarding Calderon is to do with the fact that they couldn't get Cristiano.
"Calderon promised so much that he would get the lad. Some of his comments are ridiculous. There is a complete arrogance about it all.
"There was no question of Ronaldo leaving anyway, absolutely no question."
Ferguson added: "Yes, it's possible that these are the first shots of another attempt to get him. They do it all the time. We're ready.
"We have enough ammunition ready. I'm only using one gun at the moment. I'll get the gatling gun out in January!"
