Cristiano Ronaldo continues to amaze the world of football, even at 34 years old.

The Juventus forward bagged a hat-trick in midweek that made him the all-time top scorer in European Championship qualifying.

It also pulled him closer to the all-time international goal scoring record of 109, set by Iran's Ali Daei.

Ronaldo currently has 93, putting him in second, and while most 34-year-old's would consider that target a bit beyond them, the Portuguese must think he can do it.

Because Ronaldo is no ordinary 34-year-old footballer - he appears to be ageless.

The man is still Juventus' fastest player, despite being in his mid-thirties and doesn't appear to be slowing down.

He's still scoring competitive international hattricks, for one thing.

And one of his former managers, Jose Mourinho, believes Ronaldo is so impressive that he's a case study.

"It doesn't surprise me [that he's still performing]," Mourinho told Portuguese TV, per ESPN. "At 34, he is top in the world, in a top team, in top condition. I'm not surprised whatsoever because genetically and mentally he is a case study.

"He is someone that only thinks about winning, about beating records, achieving more and becoming better. He is truly a phenomenon and it really doesn't surprise me."

And Mourinho even made a little prediction for the future - that Ronaldo will be scoring goals even after he retires.

"When he is 50 years old he will be at home and FIFA will invite him to a game of legends," Mourinho said. "He will play the game and score a goal.

"I am sure it will be like that."

It would hardly be surprising...

So for just how much longer can Ronaldo go on for? You'd expect him to be at the highest level for another couple of years, at least.

You wouldn't even bet against him performing there at 40 - he's just that special.
