Atletico Madrid president Enrique Cerezo is determined to keep hold of Radamel Falcao.
The Colombian ace is a major £40 million target for Chelsea owner Roman Abramovich.
"I would not want to trade Falcao for Lionel Messi or Cristiano Ronaldo. Falcao is the best and many teams would love to have him, but he is with Atlético and we want to keep our hands on him," said Cerezo.
