Mikel Arteta has revealed why Arsenal have signed Cristhian Mosquera. Arsenal confirmed on Thursday that Mosquera had become their fifth signing of the summer transfer window after Kepa Arrizabalaga, Martin Zubimendi, Christian Norgaard and Noni Madueke.

Cristhian Mosquera has become Arsenal's fifth signing of the off season after completing a move from Valencia.

Arsenal have confirmed the signing of Valencia centre back Cristhian Mosquera on a long-term contract. The 21-year-old adds further depth to an Arsenal backline that already boasts the likes of William Saliba, Gabriel Magalhães, Riccardo Calafiori among others, and will wear the number three shirt in north London.
