"I feel a lot of human warmth and feel like I'm becoming a son of Celtic," he told the club's official website in the wake of his Man of the Match performance in the weekend's friendly win over Liverpool.
"I'm working hard to help Celtic and the fans have given me good vibrations to give me a good impression. I am thrilled to be here.
"I'm doing my very best and the time has already gone very fast. I'm happy to be surrounded by positive energy and that is why I chose Celtic in the first place.
"I also want to thank the manager for his support and I'm learning a lot every day from him.
"I felt very good in Dublin as it's always good for a striker to score a goal. That's my work and I was impressed that, despite it being a friendly game, it was full of supporters."
