The 35-year-old former Scotland international midfielder played his final game at Celtic Park as a Celtic player on Wednesday evening, as he lined up against St Johnstone.
Brown, who joined Celtic from Hibernian back in 2007, gave a solid performance in the middle of the park and also provided an assist, as the Hoops won 4-0.
After the match, the veteran midfielder praised the Celtic fans and expressed his gratitude for their support over the years,
Brown told Celtic’s official website: “It’s a special club with special fans and it’s just sad that they’re not here today for me to say goodbye to them in person. Here’s hoping I get to come here with Aberdeen next season and I can say goodbye to them then.
“My message to the fans is: thanks for your support and for your patience. The main thing was, I came here to win trophies. Celtic fans expect trophies. We’ve done that, although it’s been a disappointing season this season.
“But, believe me, Celtic will be back and challenging next season. There are too many people at the club who work so hard to make sure there are improvements year on year, and I think that’s the best thing about this club. Plus, as soon as we get the fans back, every single player gets an extra 10 percent from them.”
