Rafael Leão is a Brazilian professional footballer who plays as a forward for the Italian Serie A club, AC Milan. Born on February 15, 1994, in São Paulo, Brazil, Leão has made a name for himself both domestically and internationally throughout his career.

Leão began his professional career with Santos FC, one of the most prestigious clubs in Brazil, where he spent five seasons before moving to Italy to join AS Roma in 2017. At Roma, he played under former Brazil national team coach, Aurelio De Stefano, who helped him develop into one of the best strikers in Europe. Under De Stefano's guidance, Leão scored 68 goals in 100 appearances for Roma.

In January 2020, Leão was transferred to AC Milan for €24 million from Roma, making him the most expensive Brazilian player ever sold to a European club. At Milan, Leão has had mixed results, scoring 18 goals in 43 appearances across all competitions, but it's been clear that he hasn't reached his full potential yet.

One of the main factors contributing to Leão's struggles is his lack of consistency. He has struggled to find his form consistently since joining AC Milan, and this has affected his overall performance. Additionally, Leão's fitness levels have also been a concern, as he has often missed important matches due to injuries or poor form.

Despite these challenges, Leão remains a talented striker and has shown flashes of brilliance during his time at AC Milan. With more game-time and improved fitness, he could potentially reach his full potential and become a key player for the club.

Overall, Rafael Leão's career progression has been marked by ups and downs, but he still has the talent to be a top-class striker in Europe. As he continues to develop and improve, there is hope that he will eventually reach his full potential and contribute to AC Milan's success.
