The 20-year-old joined the Spanish giants in a record-breaking £115million transfer from Borussia Dortmund in June.
He made his league debut earlier this month and scored in a 2-0 win over Athletic Club.
Bellingham then carried his impressive form over to Real Madrid‘s second game of the La Liga season last week when he scored twice against Almeria.
And he clinched the winning goal during the club’s clash with Celta Vigo on Friday in dramatic fashion.
The 81st minute header saw him level Ronaldo‘s total of four goals in his opening three La Liga games.
And fans have been quick to draw comparisons between the two superstars.
One person tweeted: “Two generational talents.”
Another added: “Cristiano has set the records and Bellingham is following up.”
While a third wrote: “Catching up to the champ.”
