“Ronaldo is also testimony to how combining hard work and passion can bring unexpected results. He is not the best in the world, but he trained so much to become the best. I am a fan of Ronaldo because he remained humble and he earned everything he achieved. He fought to get where he is now.”
The three-time African Footballer of the Year also described Inter Milan striker Romelu Lukaku as a more complete striker in Italy but he thinks the Belgium international is not getting the praise he deserves, a situation he compared to his own career.
