Arsenal Football Club has finalized a transfer agreement with Valencia CF for defender Cristhian Mosquera. The deal is valued at €15 million with an additional €5 million in potential add-ons, totaling $17.5 million plus add-ons. Mosquera, an 18-year-old versatile centre-back capable of playing on both the left and right sides, is expected to undergo a medical examination later this week. Arsenal secured personal terms with Mosquera prior to finalizing the agreement. The club views Mosquera as a right-footed defensive option to provide cover for William Saliba, noting his strong defensive performances against top forwards such as Kylian Mbappe and Vinicius Jr. Additionally, Arsenal is reportedly close to agreeing on a new contract with 18-year-old winger Ethan Nwaneri.
