Chelsea has entered into preliminary negotiations with Milan to explore the possibility of signing Portuguese winger Rafael Leão during the upcoming summer transfer window, amid strong interest from Arsenal as well, according to the website 'CaughtOffside.'

Leão, who is 25 years old, has a release clause of €175 million, but reports indicate that Milan may agree to sell him for an offer around €75 million, making the deal more realistic for interested clubs.

Chelsea is currently the most advanced party in the negotiations, while Arsenal is closely monitoring the situation and considers Leão as an alternative option to their primary target, Nico Williams, the Athletic Bilbao star.

Amid interest from Saudi club Al-Nassr, Leão prefers to stay in Europe, giving Chelsea and Arsenal a clear advantage in the race for his signature.

Leão is currently one of the most prominent attacking talents in Europe due to his speed, skills, and ability to make a difference in the attacking third, making him an ideal option to strengthen either team's squad for the next season.
