- Alexander Zverev has expressed frustration at feeling forced to justify his position as the new men's world number one.
- The German player reached the top of the rankings following a breakthrough season featuring his first two Grand Slam titles at the French Open and US Open.
- His rise to the top came during an injury-hit year for rivals Jannik Sinner and Carlos Alcaraz, with Zverev becoming the first year-end world number one without a Masters 1000 title in that year.
- Zverev suffered a 7-5(5), 6-2 defeat to Italy's Lorenzo Musetti at the Paris Masters, labelling it one of his worst performances in recent months.
- He will now aim to end his season on a high at the ATP Finals in Turin and the Davis Cup Finals in Bologna.
