We have a psychologist at Chelsea who goes around seeing the loan players. He said every top, top player has a dark side. So someone like Diego Costa sometimes oversteps the mark. But you can see he plays on the edge. He said I had to develop that. It's not natural for me to be like that.
This quote highlights the importance of mental toughness and the acknowledgment that even highly skilled athletes possess a darker, more aggressive side. Developing the ability to play on the edge is often essential for success in competitive sports, but it requires effort and development, not innate ability. It emphasizes the balance athletes must strike between talent and mental resilience—understanding and harnessing their darker traits to excel without crossing ethical or professional lines. Such insights remind us that greatness often involves overcoming internal challenges and cultivating a competitive edge ethically.
