Ronaldo spent the week leading up to Atletico's game bombarding Tiago and Simao with texts urging them to stun Barca.
After the result, Ronaldo told Marca: "We're now in a better position than ever before. Now, we cannot let this slip. We must be totally focused for the Liga and also the Champions League."
Gonzalo Higuain added: "We have everything to play for."
