Spaniard resumes intense rivalry with Jannik Sinner, while Sabalenka and Swiatek remain at the top of women’s game

In the endless flood of Instagram photo dumps and gushy captions from social media users around the world saluting another year gone by, Carlos Alcaraz’s efforts were particularly interesting. The candid photos from his camera roll included dozens of friends and family, various barbecues and his many haircuts throughout the year, but there was no room for one notable individual: Juan Carlos Ferrero.

The abrupt dissolution of their partnership is one of the most shocking recent coaching splits and the reaction has been dramatic. Journalists swarmed outside Alcaraz’s tennis club in El Palmar a day after the news in their futile attempts to speak with the world No 1, then Ferrero decided to give a number of interviews to offer his own side of the story.
