He told Villa's website: "I have been happy with my form and things have gone well as a unit at the back. We all joined at the same time and I think we've settled in well - that's been shown by our performances so far.
"It took a little while for me to get used to the rhythm of the team. It was a different style of play at Blackburn and I just had to become accustomed to the way the manager wanted me to play here.
"Richard and James have done well too and we've gelled well as a unit.
"Communication has been important for us. I am sure everyone can hear us on a matchday - the amount of screaming that goes on is impressive. We demand a lot of each other and it gets the best out of us."
