Okore has been able to spend time with the players and the coaching staff - and he's really been impressed with what he's seen.
He told Villa's website: "I feel good here at Villa. I feel great to have come to a team which has made me one of the guys.
"They have made me feel at home. It's like one big family. I have enjoyed my time with the lads immensely. I am so happy with them. They are really good guys.
"You can talk to the lads and get a really good relationship with them. They are easy to get on with.
"I get on with all the players. It's been a great week for getting to know them and also working hard."
