Finch Farm wasn't established when Unsworth was playing for Everton.
"It's great to see so many familiar faces and I was made to feel very welcome on my first day, I can assure you," Unsworth told evertontv.
"The facilities are brilliant, I have to say. Bellefield did have its place and at the time that was a great place to be and work, and there was a great feeling there.
"But this place has got that feeling as well because you take those characters with you - the kitmen, the ground staff and so on - and you put them in a new building and they recreate it and make new memories.
"Time has moved on and Finch Farm is phenomenal."
