Stan Wawrinka has started to struggle for form ahead of his final French Open.
Wawrinka announced that he would be retiring at the end of the 2026 season, bringing an end to his decorated 24-year career.
The 41-year-old showed some impressive form at the start of the year, with Wawrinka even making a brief return to the top 100.
However, Wawrinka has now hit a roadblock ahead of the French Open which is becoming quite alarming.
Stan Wawrinka is now on a five-match losing streak
Wawrinka is a former French Open champion, having won one of his three Grand Slam titles at the Paris major in 2015.
However, the former world number three is yet to win a clay court match this year, with Wawrinka now on a five-match losing streak.
The latest defeat for Wawrinka came at the ATP Challenger tournament in Aix-en-Provence, where he reached the final last year, losing in the first round to Sebastian Ofner.
Four of the five players Wawrinka has lost to have been ranked above him, but his defeat at a Challenger tournament in Napoli was particularly alarming.
Wawrinka was beaten by then world number 348 Matteo Martineau in Napoli, in what was his first match of the clay court season.
This is not a good sign for Wawrinka, as he looks to make his 21st appearance at the French Open this year.

What is next for Stan Wawrinka ahead of the French Open?
Wawrinka will now look to turn his form around in time for the French Open, where he is all but confirmed to be receiving a wildcard for and could even sneak into the main draw directly.
The current world number 106 is next scheduled to compete at the Italian Open, where Wawrinka reached the final in 2008.
Despite being a former finalist in Rome, Wawrinka will have to play in qualifying if he is to get into the main draw as he has not received a wildcard.
Is men’s tennis boring without Carlos Alcaraz?
Wawrinka is confirmed to be in the main draw of the Geneva Open, after receiving a wildcard for the tournament where he is a two-time former champion.
Wildcards are going to become even more necessary for Wawrinka now, as he is set to drop outside the top 120 after failing to defend his points from reaching the final in Aix-en-Provence last year.
