Martinez's buyout clause is set at €35 million.
“I am optimistic on Jackson’s move to Milan, but we’re not quite there yet,” agent Luiz Henrique Pompeo told EuroStadio.it.
“There’s no deal with the player yet. There is a good possibility we’ll conclude the transfer, but we are not yet at the all-clear moment.
“Will they pay the €35m clause? You’d have to ask Milan that, it is not something that regards us. As for the wages, I cannot discuss figures at the moment.
“What I can say with certainty is that Martinez is a player worthy of a top club and Milan wrote history.
“The Rossoneri are not just a big club, but a huge one.”
