Cristiano Ronaldo...
almost quit football forever.
At just 15 years old...
he was diagnosed with a heart condition.
Doctors told him...
his career could be over... before it even began.
He had to go through surgery.
No guarantee...
no certainty...
no future in football.
But Ronaldo... refused to give up.
Just days after surgery...
he was already back on the pitch.
Running... training... chasing his dream.
And years later...
He became one of the greatest players...
