If there was one phrase that summed up the men's tennis season, it was "Sincaraz"- the rivalry between Carlos Alcaraz and Jannik Sinner

Spain's world number one Carlos Alcaraz will miss the Davis Cup Final 8 tournament in Italy this week due to injury, the two-time Wimbledon champion announced on X on Tuesday.

Italy's Jannik Sinner and Spain's Carlos Alcaraz have met in the last three Grand Slam finals.

Carlos Alcaraz was full of smiles as he lifted the trophy for the year-end No. 1 tennis player on Friday.

It is the second time in his career that the 22-year-old Alcaraz has ended the year at the top of the rankings.

Carlos Alcaraz is one win away from securing the year-ending No. 1 ranking.

Carlos Alcaraz made a solid start to the ATP Finals on Sunday with a 7-6 (7/5), 6-2 win over Alex de Minaur.

Jannik Sinner will begin his bid to retain his ATP Finals title on Sunday and cap a turbulent year which could end with another showdown with his great rival Carlos Alcaraz.

Jannik Sinner will return to the pinnacle of men's tennis when the ATP rankings are updated on Monday.

World number one Carlos Alcaraz said he had "no feeling at all" for the ball after he was beaten 4-6, 6-3, 6-4 in his opening match at the Paris Masters on Tuesday by 31st-ranked Briton Cameron Norrie.
