Carlos Alcaraz told what he needs to work on in the off-season after suffering shock defeat to Zizou Bergs

The Spaniard suffered arguably the worst defeat of his 2026 campaign in Shanghai. Alcaraz lost to Bergs in straight sets after two hours and two minutes. He was visibly frustrated throughout, complaining to his team as he lost for the first time since the US Open (QF vs Ben Shelton). Alcaraz's error-strewn performance left many concerned, but what's next for the world number three? Serena Williams' coach, Rennae Stubbs, has now told Alcaraz what he should work on during the off-season.
