The 22-year-old joined United from Atalanta in 2023 for €70m (£60m/$77m) plus bonuses, arriving with high expectations after a breakout season in Serie A. However, inconsistent performances, injuries and tactical changes have hampered his progress. Milan see him as a strong fit for their attack and a lower-cost alternative to other targets like Dusan Vlahovic, whose signing would be more expensive and riskier financially.
