Lyon are currently rooted to the bottom of the table, having failed to win a single game this season.
Bosz was in charge of Lyon for just over one year, where he led 58 matches, finishing with a record of 27 wins, 16 draws, and 15 defeats, before being sacked in October 2022 following a run of five games without a victory.
The PSV manager, who picked up just one point in five games that led to his sack during that time at the Groupama Stadium, will be on the touchline for the Dutch side when they visit the Stade Bollaert on Tuesday as they face RC Lens in matchday three of the UEFA Champions League.
Upon his return to France, Bosz was asked about the plight of former club Lyon, and the tactician gave a cold response, saying: “I know that they’re last. It’s a shame for them, and I don’t have any other specific feeling on that.”
Lyon fired Laurent Blanc in September and was replaced by Fabio Grosso, but performances and results have yet to be an uptick. They suffered a 2-1 loss at home against Clermont Foot last weekend.
Speaking on the development, Grosso admitted that Lyon are fighting for their survival in Ligue 1.
As the battle relegation, Grosso has called on his players to step up.
Lyon remain the only side in the division without a win, while they also have the worst defence.
Meanwhile, the club owner, John Textor, has rubbished talk of relegation to Ligue 2.
The American described talk of relegation as “nonsense.”
Textor conceded that Lyon could be on for a “very mediocre” season but believes they will overcome their bad form soon.
Grosso also shared the same belief, noting that the squad has the quality to get points and move out of the relegation zone.
Rhe former Italian international has therefore challenged his lads, saying those who don’t believe in the team should step aside.
