The Ecuador international has been heavily linked with a move to the Premier League in recent weeks after scoring 12 goals in 14 appearances this season.
The Porto man has been touted as the answer to Chelsea’s goal-scoring woes, with Demba Ba, Samuel Eto’o and Fernando Torres failing to find their form.
And the 27-year-old forward, who has scored 38 goals in 44 appearances since moving to Porto, has talked up a potential move to English top-flight.
“Where would I like to play?” Martinez told La Gazzetta dello Sport. “When I was a child I rooted for Chelsea and Arsenal.
“I think the best championships are La Liga, the Premier League and Bundesliga, which has grown much in recent years.
“But I also really like Serie A and have many friends in Italy.”
He added: “My £34million buy-out clause seems a huge amount.
“In one year my value has exploded. I did not expect to do so well.”
