Pogba left Juve for United last month for a world record €100 million.
Marotta explained: “We always said we never wanted to sell Pogba, as he was an important figure for the club, the Coach and the fans. He wanted a change of scenery and to experience a different situation, so faced with that we had to enter into negotiations and try to make him happy.
“We had already targeted Higuain and he was the main image we had in our head, but it was a coincidence that this happened at the same time that Pogba asked to leave."
Mino Raiola believes soon a club will pay the first €240m price-tag for a player.
“In recent years the figures have climbed rapidly, even to an illogical degree. Mind you, revenues have increased, individual clubs have big backers and this money is ploughed into the transfer market as well as the wages.
“In England clubs have far more available money than the other Leagues, so that skews the market."
