AC Milan are active in the market, having already signed several players and still planning for more mercato shots. But, sales are also in the agenda of the team, even after the exits of Sandro Tonali as well as Daniel Maldini on loan.
According to what is reported by Calciomercato.com, the Rossoneri's players Lorenzo Colombo and Matteo Gabbia will leave in this summer's transfer window. However, they will not exit the club before the end of the American tour.
In fact, the plans of the Rossoneri club are to include them in the squad for the trip to the United States of American and then let them leave on a loan transfer.
I don’t think it would be possible to sell or rent out all the academy players who are qualified to play first-team football because they are vital to meeting the league and Champions League entry rules, which is a scarce resource.
