Belgium striker Jelle Vossen wants to repay Middlesbrough fans for the online show of support that accompanied his eventual move from Genk this summer.
Vossen, 25, had been a Boro target for at least a year but did not complete his season-long loan move until the end of the transfer window.
Meanwhile, Boro fans had set up a Twitter campaign in a bid to bring the 12-cap international to the club.
"It was amazing, I never thought it would be so big," Vossen told BBC Tees.
"It was great to follow on Twitter and there were a lot of fans involved.
"I'm very happy to be here and I hope to give them something back as fast as possible."
During a four-year spell with Genk, the Bilzen-born forward scored 105 goals in 244 games.
Despite leaving a club in Belgium's top flight to play in the second tier of English football, Vossen sees his switch to the Championship as a move up the football chain.
"It's a different way of playing. I had 13 years at Genk and I needed a new challenge so that's why I'm here," he said.
"Obviously the facilities in England are amazing, the stadium and the training ground are excellent and it's a step forward out of Belgium."
