The Portuguese international recognised that the only person that can decide is coach Frank Rijkaard, but promoted his teammate's cause to be included on Sunday.
Ronaldinho remained on the bench as Barça defeated Valencia last weekend, but there is a concensus building that he should play against Madrid and Deco agrees.
"The players that are ready have to play and I think Ronaldinho is in good condition;" he said. "But it is still down to the coach to decide."
Despite adding to the debate, Deco then explained that he preferred it the build-up was not all about whether one player is picked or not.
"It takes away the focus from what is really important and while we talk about this, they take advantage in Madrid," he explained.
"What is important is the team and I think that now we are in a good moment.
"We are training hard and are motivated, so we should not cause ourselves problems."
Deco then reflected on the draw at Camp Nou last term against Madrid and believes that Barça should learn from the mistakes that they made that day.
"Last season they scored three goals against us and caused us a lot of problems on the counter-attack. We have to be careful. We know what they can do," he concluded. /Goal.com
