Chelsea has confirmed the signing of Italian wing-back Marco Palestra from Atalanta and the return of striker Nicolas Jackson after Bayern Munich declined to activate his buy-out clause.

• Palestra arrives on a seven-year contract in a deal worth £47 million.
• Key individuals involved include new head coach Xabi Alonso, Marco Palestra, and Nicolas Jackson.
• Jackson returns to Chelsea after failing to meet the appearance threshold for his loan at Bayern Munich, where he managed only around 15 appearances.
