Arsenal are in talks to sign defender Cristhian Mosquera from Valencia.
The Gunners want to make a defensive signing this summer and the 20-year-old Spaniard, who can play at centre-back and right-back, is emerging as their favoured option.
Arsenal have shown interest in Marc Guehi of Crystal Palace, but the England international may be reluctant to join given that he may find opportunities limited behind Gabriel Magalhaes and William Saliba.
Spain Under-21 international Mosquera has made 90 appearances for Valencia and was a regular in the team last season, playing 90 minutes in 37 of the club's 38 La Liga games.
