The Kenyan midfielder was signed from Belgian side Beerschot by Neil Lennon and went on to become a Parkhead favourite over two seasons.
A standout moment was opening the scoring with a bullet header as Celtic went on to stun Barcelona in the Champions League, with Tony Watt getting the winner.
Wanyama went on to earn the club a massive profit on the £900,000 they spent on him when he moved to Southampton for £12.5million.
After that, he followed Mauricio Pochettiono to Spurs and played in the Premier League for a total of seven years.
However, it is Celtic he holds most affection for.
Speaking to The East African, he said: “I was treated well in every European club I played for. But I think where I experienced more love was in Celtic. The fans there adore me so much. It was a beautiful feeling and experience.”
However, it would seem he didn’t make much friends along the way, adding: “Contrary to what many think, football isn’t a sport where you get to make friends. The friendship in football is different. Yes, you may get along with fellow teammates, but there isn’t really a time when you can develop a mutual bond with a teammate because of the nature of the sport.
“One minute you could be playing for this team, and the next you have been sold to a different club, and so you go there to start life anew. Or the teammate you thought you were close to moves to another club. Besides, in Europe, no one has time for you, and that makes you realise just how important your family is because they will always be there for you. This explains why you will always find me in the company of my family members. I am very close to all my siblings.”
