“I don’t need to explain myself or say why I came here, people just saw in the game and they know why I came here.
“It was the right thing for me and the right choice.
“Celtic is a family club, so there’s a special relationship between the players and the fans and you cannot see this at any other club in the world.
“I’m glad to be here and have this family around me.”
Dembele, who cost a £500,000 development fee after arriving at Craven Cottage as a 16-year-old from Paris Saint Germain’s youth side, added: “As soon as I heard from Celtic, I spoke with my family and we decided to come here.
“Even after this, I tried to look at everything about the club and tried to learn a bit about the club.
“I knew some things, but I wanted to learn more because I knew I would come here and, at the end of the day, it’s the best decision I have made. I know I’ll keep improving if I keep playing big games.
“As a young player, this is a good thing and, hopefully, I can keep scoring goals in the Champions League, the league, the League Cup and everywhere!”
