The Portuguese star scored a memorable goal in Real's 6-0 demolition of Real Zaragoza as his side closed the gap to leaders Barcelona to just two points ahead of the winter break.
"I'm working well and I want to carry on this way until the end of the season. I'm doing better every day. I missed two months and coming back was difficult, but things are working out for me," Ronaldo told the club's official website.
"It was important to seal the year with a victory, so we are happy about that. We must now think of the New Year, which we should start as well as we've ended this one."
Then Ronaldo, returning after a one-match suspension, teased the Zaragoza defence before adding the fifth and substitute Karim Benzema wrapped up the scoring with 20 minutes to go.
A victory at the Riazor would have put Valencia in third place, behind Barcelona and Real Madrid, while Deportivo also had the chance to move into the top four, but the game failed to live up to its billing.
Depor shaded the match thanks in part to the excellent Juan Carlos Valeron but Valencia's strong organisation made them difficult to break down.
Valencia stay in fourth spot, 10 points behind leaders Barcelona while Deportivo are sixth, 12 points off the top.
Juan 'Nino' Martinez put Tenerife ahead after three minutes, converting a knockdown by Alejandro Alfaro, but Jose Jurado equalised for Atletico, who were without their talismanic striker Sergio Aguero through injury.
Nino missed several chances to give Tenerife victory, none better than a penalty before half-time which goalkeeper Sergio Asenjo parried well.
Fernando Fernandez seized on a loose ball in the area to score after 23 minutes but Mallorca equalised through Julio Alvarez and were in the ascendancy when Malaga, who had not won since the first week of the season, struck again with Fernando Forestieri heading home.
Villarreal continued their upward march with a 2-0 win over Racing Santander, their third victory in succession.
Nivaldo Batista cancelled out a goal from the visitors by Luis Moran and the winner from Medunjanin was no more than Valladolid deserved, having squandered a number of gilt-edged chances.
