Los Colchoneros are expected to have a huge war-chest to strengthen their return to the Champions League made possible by selling star Radamel Falcao to one of his rich European suitors.
After Suarez's latest controversy, as he bit Chelsea defender Branislav Ivanovic, Atletico have been linked with a move for the Uruguayan and could make their interest concrete if the coach has his way.
"I cannot speak badly about Luis Suarez, he is extraordinary," Simeone told a press conference.
"But we have a game coming up that means we have to leave other matters aside."
Simeone was asked about other potential summer targets and spoke candidly about his admiration for River Plate's Augusto Fernandez, who he coached at the club in 2008
"He's grown an enormous amount; as a young player he performed well and he's one of the key players alongside Iago Aspas," he added.
