Buendia has been snapped up on a five-year deal from Norwich, for a fee which could rise to £38million.
He is excited to get going at Villa Park, too, after lots of positive conversations with compatriot Emiliano Martinez about the club.
“He already told me about a lot of the club and the city," said Buendia. “He told me a lot of very good things about everything. Of course, to have someone like him is very good for my adaptation. So it will be better.
“But, already, it's my fourth year in England so I can speak with every team-mate like normal.
“He told me about the very good group in the team, they are good people there. So I think it will be easy for me."
Buendia was Villa's number one target this summer and they managed to get him ahead of Arsenal.
