The striker joined Inter last week after signing from Santos in August.
"For the project," Gabigol told Fox Sports when asked to explain why he chose Inter.
“Inter want to return to being a very strong team. Because of that, I decided to go to Italy with my family.
“I am happy with my choice, I think I have come into a great team which I have always heard good things about. This is why I preferred Inter to Juventus.
“I decided to leave Santos because I thought I had stayed for quite a long time and learned quite a lot of things. I did what I felt was right."
