Arsenal have confirmed the signings of Shkodran Mustafi from Valencia and Lucas Perez from Deportivo La Coruña.

Mustafi becomes their sixth summer recruit after Granit Xhaka, Rob Holding, Takuma Asano - who has already joined Stuttgart on loan - and Kelechi Nwakali.

Mustafi will improve Arsenal's central defense while Perez gives them another attacking option.
