Zverev becomes world number one, loses Paris opener and calls reaction 'annoying'

Alexander Zverev has become ATP world number one, lost his first match at the Paris Masters, and called the reaction "annoying".

• Zverev moved to the top of the ATP rankings on Monday after winning this year's French Open and US Open titles.
• He lost 7-6 (7-5), 6-2 to Italy's Lorenzo Musetti in the Paris Masters second round on Wednesday, his first match since the change.
• Zverev said he has been "annoyed" by the reaction, claiming he is the only player in tennis history forced to explain why he deserves number one.
• Zverev holds a 62-8 record against opponents ranked 11th or below this year but has won only three of 12 matches against top-10 players.
