Arthur Fils has been impressive since returning to the ATP Tour for the first time in seven months at the beginning of the year.
The Frenchman reached the quarter-finals of Indian Wells and went one better by reaching the final four of the Miami Open.
Fils’s new partnership with Goran Ivanisevic has shown glimpses that he could soon become a top 10 player.
However, the 21-year-old has shown a weakness since his return and he’s revealed what he wants to do to change it.
Arthur Fils highlights his current biggest weakness
Fils performed spectacularly to defeat Tommy Paul in the Miami Open quarter-finals, which was decided by three tie-breaks.
Alternatively, Fils looked out of sorts as he crashed out of the tournament at the hands of Jiri Lehecka in the semi-final.
Who is the better tennis pundit – John McEnroe or Andy Roddick?
Many have questioned Fils’ stamina following the tournament, and it’s an issue the Frenchman is well aware of.
Speaking to L’Equipe, he said: “I know I need a lot of energy to play my best tennis . But do I need that much? I don’t know. It certainly makes me play incredible matches.
“But then, it can also take its toll on me sometimes in subsequent matches. I was a bit down today . But these things happen.
“It’s a balance that isn’t easy to find. We need to find solutions because I don’t want to change my approach.”
Fils is up to world number 28 in the ATP Tour rankings after reaching the semi-finals of the Miami Open.
Justine Henin questions Arthur Fils’ defeat in Miami
Seven-time Grand Slam champion Justine Henin was one of those commentators who was critical of Fils’ performance against Lehecka.
Fils won just four games against the big serving Czech star, but Henin believed the Frenchman was lacking physicality.
If you were in charge of tennis, what is the first rule you would change?
Speaking on Eurosport, the Belgian said: “Physically, he was far from his best. He couldn’t recover from his efforts on the physical level, nor on the nervous level either.
“He has that fiery temperament,” she added. “It’s an asset, but it can also, at times, drain quite a bit of his energy.”
Fils will now head closer to home as he tackles the European clay court season, with his first tournament set to be the Monte Carlo Masters.
