Porto striker Jackson Martinez has poured cold water on speculation linking him with a move to Borussia Dortmund, insisting that he is happy in Portugal.

Martinez scored 26 goals in 30 league games for Porto last season in his debut campaign for a European club.

Despite rumoured interest from Dortmund and Napoli, the Colombian striker is adamant that he will spend next season with the Portuguese champions.

He told Renascenca: "I am happy to be here at a club like this. I am enjoying the opportunity to play here.

"I want to repeat what happened last season and win more trophies with Porto."

The 26-year-old is currently contracted to Porto until 2016.
