Thierry Henry suffered defeat in his first match as a head coach when his 10-man Monaco side slumped to a 2-1 loss at Strasbourg on Saturday to drop into the Ligue 1 relegation zone.
Monaco parted ways with Leonardo Jardim last week, and turned towards Henry – who began his playing career at the principality club – as their new coach with the club 18th in Ligue 1.
However, Monaco winless run stretched to 11 games on Saturday, having not won since the opening weekend of the French top-flight season, and they are now only above bottom-club Guingamp on goal difference.
A dreadful error by Monaco’s third-choice goalkeeper Seydou Sy gifted Strasbourg midfielder Adrien Thomasson an early opener, and substitute Samuel Grandsir was sent off midway through the second half.
Lebo Mothiba doubled the advantage, and a late Youri Tielemans penalty was a mere consolation for the 2017 Ligue 1 title-winners.
Meanwhile, Paris Saint-Germain continued the blistering start to their Ligue 1 title defence with a record-extending 10th straight win as Kylian Mbappe scored in a 5-0 thrashing of Amiens.
Coach Thomas Tuchel left key men Neymar, Thiago Silva and Thomas Meunier out of the squad altogether at the Parc des Princes with Wednesday’s Champions League clash with Napoli in mind, but PSG had more than enough to see off Amiens, with Mbappe scoring his 11th goal of the campaign.
Elsewhere, second-placed Lille continued their strong start to the campaign as goals from Nicolas Pepe and Luiz Araujo sealed a 2-1 win over Dijon.
