The forward said: "I didn't have to think long about it when I heard about Hearts' interest, I wanted to come here as my number one choice.
"I have the same agent as Peter Lovenkrands, who played at Rangers, and we talked a little. I wasn't in any doubt. I wanted to come here because I have been following Scottish football.
"The football here I've always been very impressed with because it's very physical, strong football. That's one of my strengths.
