An alternative to Camavinga if Arteta wants a senior option ready to start immediately (similar to Partey this season) could be Fabian Ruiz at Napoli. Think he would be a fantastic addition: contributes to both offence and defence, can pass, dribble and shoot. Mobile, powerful and has great stamina. Strong in duels and tough in the tackle. Intelligent. Can play in a two and three. Left-footed too. Pretty sure he displaces Xhaka immediately.
