Ronaldo thinks the Spanish youngster will be a superstar and deserves more game time.
Asensio broke into the Real Madrid team last season, stared in the European Under-21 Championship this summer and started this season with a bang.
The 21-year-old has made three La Liga starts and has come off the bench twice.
He scored twice in the 2-2 draw with Valencia and hit in both legs of the Spanish Super Cup against Barcelona.
But despite his impressive form Real have struggled at the start of the season and find themselves in the midst of an early season crisis.
They currently sit seven points behind Barcelona after just five games.
Ronaldo made his first league appearance in the defeat to Betis on Wednesday after his five-game ban.
And now he wants to be playing alongside Asensio.
The 21-year-old played just 23 minutes against Betis and Ronaldo wants him starting games ahead of Gareth Bale and Borja Mayoral.
Don Balon claim Ronaldo doesn’t rate Mayoral and doesn’t want him near the team, and he is concerned with Bale’s form and thinks Asensio should now be first choice.
Ronaldo wants to play in a front two with the young Spaniard and believes that is now the club’s best formula for the season.
The Portuguese thinks playing with Asensio gives him the best chance of catching Lionel Messi in the goalscoring stakes – despite already being nine behind.
