Steven Milne (right) was seven seasons with Dundee

The 25-year-old had made only 12 substitute appearances for the English Championship outfit after joining from Dundee last summer.

Milne had made 117 appearances, more than half as a substitute, in seven seasons at Dens Park.

Saints boss Owen Coyle said: "Steven is a proven goal scorer at SPL level and I think the fans will enjoy seeing him."

It is Coyle's fifth close-season capture, having already signed defenders Kevin James and Mark Campbell from Falkirk, striker Stephen Dobbie from Hibernian and midfielder Neil Janczyk from Hearts.

"This signing came about as a result of a chance conversation I had last week, during which I learned that Steven might be available," Coyle told his club's website.

"We've done all in our power as a club to move quickly and bring Steven to Perth and I delighted to have succeeded.

"I said I wanted a player that would complement the existing strikers and I know I have found that player in Steven.

"I would like another couple of new faces and the wheels are in motion, but whether that is before or after pre-season training commences remains to be seen."
