Aberdeen has signed former Scotland left-back
The 33-year-old follows
Naysmith, who has 46 caps, will go into the squad for the Scottish Premier League opener against Celtic this weekend.
Naysmith began his career at Hearts and has been in
The experienced fullback said he was relishing a return to Scottish football after over a decade plying his trade in England.
"The game has changed since I was here, the last time I played in Scotland was 2000 - every club seemed to have experienced players but now it seems most clubs have young lads so it is a completely different environment," he told Aberdeen's RED TV.
"A lot of people think you can get fed up playing the same teams all the time but I'm looking forward to coming back and playing in Scotland again because I have been away for 12 years and it is something I'm looking forward to."
Naysmith was released by Huddersfield at the end of his contract after two seasons in West Yorkshire.
He revealed former international team-mate and current Dons captain Russell Anderson made manager Craig Brown aware of Naysmith's availability.
He said: "It seemed to take a while to eventually get a club after I knew I was going to be released by Huddersfield. There were various bits of interest but I had just been training myself.
"I always kept in touch with Russell Anderson since we were in the under-21s together. I spoke to him and he asked what I was up to and I said I still hadn't got anything sorted and he said he would mention it to the gaffer.
"The gaffer phoned me and he was up-front, he told me he had another couple of irons in the fire and he didn't know about my availability but would keep me posted if something didn't happen with the other players."
Brown then invited Naysmith on the club's pre-season tour of Germany, an opportunity the defender was not going to turn down.
"It was a no-brainer really because at the worst I was going to get 10 days of football training and a little bit of the games, so it was only going to bring my fitness on if nothing got sorted at Aberdeen," he said.
