The 26-year-old scored on his debut with only his second touch in English football, and has weighed in with another two goals since.
"He's good in the air, good with the ball, has pace and is strong - he's a bit like Torres. They have the same kind of qualities," assessed Pedersen.
"It's good to play with him, and good to have a player like him on our side. I'm glad he signed for us.
"He's a bargain from what I've see him of him so far. He's been brilliant for us.
"Although he can score goals, I don't think we've seen the best of him yet. He's just going to get better and better.
"Once he gets to know us better, then hopefully he can give us more."
