Apart from this, he also shed light on Jannik Sinner's success and the judgment that he was facing despite reaching impressive feats."The defeat in New York, in my opinion, is not so surprising. At that moment, Alcaraz (Carlos) was psychologically, physically, and mentally better than Jannik (Sinner)" he shared, as per Corriere dello Sport.He continued:"However, we must not forget that he too went through five difficult months, and to think that today people are trying to portray Sinner as a player in crisis after he won two Slams in a year and reaches finals every week. He is doing extraordinary things and then we, like everyone, always want to improve."Simone Vagnozzi played thirteen years on the ATP Tour and had a career-high ranking of World No. 161 in the singles category and World No. 74 in the doubles category, as per the ATP Tour's official site.Simone Vagnozzi positively reflects on coaching Jannik Sinner with co-coach Darren CahillSimone Vagnozzi and Darren Cahill with Sinner at the Cincinnati Open 2024 - Final Day - Source: GettySimone Vagnozzi shared how he works in harmony with co-coach Darren Cahill for Jannik Sinner's overall development.
