Alex de Minaur was knocked out by Flavio Cobolli in the fourth round of Wimbledon on 5 July 2026, prompting former Andy Murray coach Mark Petchey to demand a coaching shake‑up.

What happened at Wimbledon?

De Minaur entered the All England Club as the world No. 6, hoping to improve on his 2024 quarter‑final run. He met Italy’s 23‑year‑old Cobolli in a straight‑sets battle, 6‑4 7‑5 6‑2, and walked off the court without a break point in the final set. In the post‑match press conference he reiterated his loyalty to longtime coach Adolfo Gutierrez, who has guided him since age nine.

Why is Mark Petchey pushing for a new coach?

While de Minaur defended Gutierrez, Petchey, now a Stan Sport analyst, argued the Australian needs “a voice with more passion.” He recalled his own emotional loss to Sandon Stolle, saying a “hype man or hype woman” could reignite de Minaur’s fire. Petchey pointed to the player’s 0‑13 record against Jannik Sinner, 0‑6 versus Carlos Alcaraz and 1‑3 versus Novak Djokovic as evidence that something in the current setup isn’t clicking.

How could a coaching change affect his game?

Gutierrez has overseen 11 ATP titles for de Minaur, including back‑to‑back wins at the Mexican Open (2023, 2024) and the Rotterdam Open in 2026. Yet the Grand Slam tally remains limited to quarter‑final appearances at the US Open (2020, 2024, 2025) and the French Open (2024). A fresh perspective might bring new tactical tweaks—perhaps more aggressive net play or varied serve patterns—to break the dead‑lock against the sport’s elite.

What does de Minaur say about his future?

During the Wimbledon interview de Minaur admitted the loss felt “like a golden opportunity slipping away,” but he also emphasized the trust he has built with Gutierrez over 15 years. He hinted that any decision will be taken after the summer hard‑court swing, suggesting he wants to assess his form at the US Open before making a move.

What’s next for the Australian?

De Minaur will head to the North American hard‑court season, targeting the US Open where he hopes to finally break past the quarter‑final barrier. Meanwhile, Petchey’s comments have already sparked debate on social media, with former players weighing in on whether a coaching change could be the catalyst de Minaur needs to finally capture a Grand Slam title.
