Andy Murray opted to work with iconic American tennis coach Brad Gilbert in 2006 as he looked to join the ATP elite.
Murray was considered one of the biggest young talents in the sport at the time, and he opted for Gilbert, who had previously worked with Andre Agassi and Andy Roddick.
The Scot did not win a Grand Slam under Gilbert, but he did crack the top 10 of the ATP Tour rankings for the first time.
Murray won three tournaments under Gilbert, but the pair reached breaking point after the Scot lost the Metz final to Tommy Robredo in 2007.
Andy Murray’s argument with Brad Gilbert
Murray played in his sixth ATP final at the Metz Open, but things didn’t go to plan against then-world number nine Tommy Robredo.
The British star had a dream start in the final by winning the first set against his Spanish counterpart, but things started to unravel after that.
Robredo won the next two sets 6-2 6-3 to lift the trophy and things became tense between Murray and Gilbert.
Where does Andy Murray rank among the best players in tennis?
The pair had an argument after the final, which led to Murray storming away from his American coach in the city.
Speaking about the argument in 2015, Murray said: “It got pretty heated in the car. I actually got out of the car and walked back to the hotel. It was a lot further than what I thought it was.
“It was 10, 15 minutes in the car, but more like a 45-minute walk, and I didn’t really need that after playing a three-set match.”
Murray bounced back from the disappointing defeat immediately by winning the St. Petersburg Open in the same month.
Andy Murray and Brad Gilbert’s strained relationship
Murray and Gilbert’s relationship reportedly soured before they split in 2007, with their argument in Metz not the only time they came to blows.
Speaking to Sky Sports in 2008, Gilbert said of his time with Murray: “There was a big age difference and a culture difference.
“Andy is very argumentative if he feels strongly about something. A lot of people in his team gave in to him. I didn’t so we would argue, about sports mostly.”
Gilbert went on to work with Kei Nishikori, Sam Querrey, and Coco Gauff before stepping away from tennis coaching.
