Kylian Mbappé scored the winner for France against Turkey before being forced off with an apparent knee injury just minutes later.
What looked like the perfect start to Zinedine Zidane's reign quickly turned into a worrying evening for France and Real Madrid.
Mbappé gave Les Bleus the lead early in the second half, but the France captain was unable to finish the match after suffering discomfort around his left knee.
Mbappé Scores the Winner
France had controlled much of the possession without finding a way through Turkey's defence during the opening half.
That changed in the 54th minute.
Michael Olise found Mbappé in space, and the striker produced a calm finish to put France ahead.
The goal appeared to settle the visitors and gave Zidane the breakthrough he had been waiting for in his first competitive match in charge.
But within minutes, attention shifted away from the goal.
Mbappé Forced Off Minutes Later
Mbappé received treatment shortly after scoring.
He initially tried to continue but soon went down again and signalled that he could not carry on.
Désiré Doué replaced him as France were forced into an early second-half change.
Mbappé left the field walking, but his visible discomfort immediately raised concerns about his condition.
The fact that he was able to leave the pitch without assistance was encouraging, but the seriousness of the injury remained unclear.
France and Real Madrid Await Updates
The timing of the problem is far from ideal.
Mbappé is one of the most important players for both France and Real Madrid, and any absence would be closely monitored by both teams.
France have more Nations League fixtures ahead, while Real Madrid are also entering a demanding part of the club season.
Until an official medical update is released, the exact nature of the injury remains uncertain.
That means any claims about recovery time or the specific type of knee problem would be premature.
France Hold On for Victory
Despite losing their captain, France remained composed and protected their narrow advantage.
Turkey pushed forward in search of an equaliser, with Arda Güler involved in several dangerous attacks.
Mike Maignan produced important saves when required, while the French defence managed the closing stages effectively.
Turkey's hopes were reduced further late in the game when goalkeeper Uğurcan Çakır was sent off following a VAR review.
France eventually closed out the 1-0 victory.
A Mixed Night for Zidane
Zidane could hardly have asked for a better result in his first match.
France won away from home, kept a clean sheet and started their Nations League campaign with three points.
But Mbappé's injury changed the mood completely.
The France captain had provided the decisive moment of the match.
Now the bigger question is whether that goal came at a cost.
For France and Real Madrid, the focus will quickly turn to Mbappé's fitness and whether he will be available for the matches ahead.
