The agent of Porto striker Jackson Martinez has said that his client is set to complete a move to a "big European club".
The 28-year-old has enjoyed a productive three years in Portugal, but in recent months he has been strongly linked with a transfer to Arsenal or AC Milan.
"Jackson's future is already pretty much decided," representative Luiz Henrique Pompeo told O Jogo.
"Things should be clarified in the next few days. He'll go to a big European club, which will be announced as soon as the contract is signed. From what's been agreed, Porto will receive the €35m (£24m) from the release clause.
"Negotiations have been underway for a few weeks, there are still some details to be sorted out, and then Jackson Martinez's departure from Porto can become a reality."
Martinez has scored 92 goals in 132 games for Porto.
