Porto president Jorge Nuno Pinto da Costa recently challenged Cristiano Ronaldo to get to 1,000 career goals before he retires.

Ronaldo, 38, currently holds the world record for the most goals scored by a single player in soccer history, having netted 857 times in 1,187 senior games for Sporting Lisbon, Manchester United, Real Madrid, Juventus, Al Nassr and Portugal.

When asked last week if Pinto da Costa’s target of 1,000 was achievable, Ronaldo responded cautiously.

Ronaldo said: “It’s going to be pretty tough, but it’s about seeing how I am mentally, my motivation.

“If, physically, my legs treat me as well as I treat them? We’ll see.

“There are small stages. Before I can go for 1,000, first I have to get to 900. I think I’ll get there.”

Ronaldo’s 857 career goals have been scored at an average of 0.72 per game.

Using that strike-rate, he would have to play another 198 matches to get the 143 goals needed to reach 1,000.

Ronaldo has played an average of 51 games per year in the past five years.

Therefore, if he keeps playing and scoring at a rate consistent with what has gone before then Ronaldo would need to continue for almost another four years to get to 1,000 goals.

That sounds somewhat unlikely, considering Ronaldo will be 42 in four years.

Ronaldo said back in June that he expects to retire from his playing career in “two to three years maximum”.

Should he stick to that retirement plan then he will need to significantly accelerate his rate of scoring if he is to get to four figures.

He has scored 31 times in his first 36 appearances for Al Nassr, averaging 0.86 goals per game. However, his record since the start of the 2023/24 season has been a round 17 in 17.

Let us imagine he can keep that goal-a-game ratio going indefinitely. In this scenario, Ronaldo would only need to feature in another 143 games to get to 1,000.
