Luis Palma has sent an emotional message to Celtic fans following his exit for Lech Poznan.
The Polish side triggered the option to buy that was included in the Honduran winger's loan spell, after he did enough to convince them to splash a club record fee.
They announced the permanent signing last week, with Celtic catching up and confirming Palma's exit this week.
The 26-year-old has now broken his own silence on a "special chapter" of his life, telling supporters he will always be one of them.
He said: "Today, I say goodbye to a club that marked a very special chapter in my life.

"Since I was a child, I dreamed of playing in stadiums like Celtic Park, experiencing unforgettable European nights, and representing an institution as great as Celtic F.C. By the grace of God, that dream became a reality.
"I would like to sincerely thank everyone who made my journey at this club possible: the board, coaches, teammates, technical staff, and every person who works behind the scenes. Thank you for your trust, support, and for helping me grow both as a player and as a person. I leave with unforgettable memories and friendships that I will cherish for the rest of my life.
"To the fans, thank you from the bottom of my heart. From day one, I felt your love and unwavering support. I will always be one of you."
Palma signed for Celtic from Greek side Aris in 2023 and had a fast start before fading towards the end of his first season, but finishing the campaign with 10 goals.
The 2024-25 campaign saw him play just eight times before completing a loan move back to Greece with Olympiacos. Then followed the loan move to Poland and he will now hope to continue the solid start he has had there.
