Aberdeen manager Jimmy Calderwood is delighted to be bringing Derek Young back to the club on a two-year deal.
Young played in the First Division with Partick Thistle last season
"He is an absolute gem, a great lad to work with, everybody at the club knows him and he is very popular," Calderwood told the Press & Journal.
"The fact we are able to bring someone of Derek's quality with the budget restraints we have is very pleasing.
"He is very versatile and is another player who will give you everything he has got."
The 27-year-old midfielder began his career at Pittodrie and made 129 appearances for the Dons between 1998 and 2003.
And it was Calderwood who lured Derek, and his brother Darren, away from Pittodrie, when he was in charge of Dunfermline.
Following three seasons at East End Park, he started last term at St Johnstone but moved on to First Division rivals Partick Thistle.
Young made 31 appearances for the Jags, scoring five times.
Young, who was training with Hamilton Accies before Calderwood approached him, said: ""It's been fairytale stuff for me and I'm still taking it all in.
"It will take me a couple of weeks to get my fitness up as I have not played at all during pre-season."
