Shkodran Mustafi deal takes transfer window spending past £1bn

The central defender, 24, arrives after Arsene Wenger’s near summer-long pursuit, and shortly after Calum Chambers’ loan departure to Middlesbrough.
Arsenal had earlier secured the signing of Lucas Perez from Deportivo La Coruna, so Germany’s Mustafi becomes their sixth summer recruit after Granit Xhaka, Rob Holding, Takuma Asano — who has already joined Stuttgart on loan — and Kelechi Nwakali.
