Ronaldo scored a hat trick in Madrid's 4-0 win over Getafe, netting in the 62nd, 65th and 72nd minutes after Sergio Ramos opened the scoring shortly after halftime. Ronaldo was replaced by Karim Benzema following his third goal, but Karanka pointed out that Ronaldo is not hurt and that his performance should remove any doubts about his fitness.
"[We used] ice as a precaution and we haven't removed it. His performance is there for all to see. Just look at the goals he scored," Karanka told reporters.
Antonio Adan kept a clean sheet in the first match since Iker Casillas' injury ruled him out for up to the next 12 weeks, and the goalkeeper was delighted to see Ronaldo return to aid Madrid's second-half improvement.
"I didn't have much to do and I'm happy with my performance. We were sluggish with our play in the first half but we still had chances," Adan said. "In the second half, we put right everything that we failed to do initially. Their goalkeeper was the man of the match."
Real Madrid sits third in the Spanish Liga table on 43 points after Sunday's victory, temporarily closing the gap on Barcelona to 12 points, although the Blaugrana have a game in hand and play relegation-threatened Osasuna later on Sunday.
