Odsonne Edouard has opened up on his "disappointment" at being unable to make it at Paris Saint Germain.
The forward came through the youth system at the French giants but was unstable to establish himself in the first team.
After a loan spell at Toulouse in Ligue 1 he arrived at Parkhead on a years deal in 2017 before joining permanently the following campaign.
And while Edouard does not regret moving to Glasgow, he is disappointed it did not work out at PSG.
Speaking to Palace's official website, he said: "I joined Toulouse FC on loan. I felt the need to quickly acquire professional playing time, especially in Ligue 1.
"At that time, it was very complicated to establish myself on the Paris Saint-Germain attack front.
"Zlatan Ibrahimovic then Edinson Cavani piled up the goals! When I returned to the club, the coach told me that he was not counting on me because he had recruited Hatem Ben Arfa and Jesé in attack, more experienced players.
"So I decided to try my luck elsewhere, which is how I signed for Celtic FC. It's more of a disappointment than a regret, because I would have loved to step onto the pitch at the Parc des Princes with the red and blue jersey.
"Everyone makes their own way depending on the context of the moment!"
