'Stefanos Tsitsipas wants to become No. 1 player,' said his psychologist

Stefanos Tsitsipas claimed his first Masters 1000 title on Sunday in Monte Carlo, beating Andrey Rublev in straight sets to add the second notable crown to his tally after the ATP Finals.

Always highlighting the importance of the mental aspect, Stefanos has been working with psychologist Costas Pergantis since the age of 12, improving that element of his game to become one of the world's greatest players. Praising his pupil, Pergantis said that Stefanos wants to become world no. 1 and chase high goals.

"Right now, Stefanos is the Tour's strongest athlete. Medvedev, who is ranked higher than Stefanos, is taller but does not have the somatometric characteristics of the Greek player.

The Russian doesn't have Stefanos' proportions or the all-court game. Apostolos and the rest of his team did a great job. They prepared the right tactic for the final, and Stefanos knew what he had to do to disarm Rublev.

When everyone in the team does their job nicely, the results should come. Stefanos wants to become world no. 1 one day; he is not happy of reaching the top-3 or top-2. Still, the final step is also the most difficult one to climb. Nadal and Djokovic couldn't challenge Stefanos in Monte Carlo, and he didn't think about that, staying focused on his game and the next opponent. No matter what we say or do, Stefanos is the one who has to step on the court and show good tennis, which he did," Costas Perangtis said.
