We are delighted to announce the signing of talented young left-back Riccardo Calafiori from AC Milan on a long-term contract. The 21-year-old Italy Under-21 international joins us after impressing at youth level and making his professional debut for the Rossoneri last season. Calafiori, who has also been capped by Italy at various youth levels, is known for his pace, energy and attacking prowess from full-back, as well as his defensive solidity. We are excited to welcome him to our squad and believe he will be a valuable addition. He will wear the number 33 jersey. Calafiori said: ‘I’m thrilled to join Arsenal and I want to thank everyone involved for giving me this incredible opportunity. I’ve always been fascinated by the club’s history, philosophy and values, so it’s an honour to become part of this family. My goal is to contribute positively and help the team achieve great things.’ Mikel Arteta added: ‘Riccardo is a very talented young player with a lot of potential. He has impressed us with his performances on the pitch and his willingness to learn and improve. We’re looking forward to working with him and helping him develop into an top-class left-back.’
