Despite Bournemouth's relegation, Sam managed to score 12 goals last season in their efforts to stay in the league 1.
Quoted from the official Wolves website "I had heard that other clubs were linked with me, but I was flattered when I heard of the Wolves' interest," said Sam.
"The first thing I knew of anything definite was after the Wales under 21s game with England. The gaffer, Mick McCarthy, had been to watch me."
"Wolves are always at the top end of the Championship and a club of this size deserves to be in the Premier League."
