Overview

• Arsenal signed Mosquera from Valencia for about £13 million to provide competition and cover for William Saliba at centre-back.
• After Saliba was injured at Anfield, the 21-year-old stepped in and impressed, including a composed showing in the win in Bilbao.
• He has won eight of nine ground duels (88.9%), the best in Arsenal’s squad and the highest in the Premier League among players with at least 200 minutes, and has misplaced only 11 of 143 league passes.
• Team-mate Jurrien Timber praised his ease on the ball and defending, while Peter Crouch called him “very good” and Darren Bent said he looks “equally as good” as Saliba.
• Reports indicate Mikel Arteta is set to restore Saliba against Manchester City, with Mosquera likely on the bench, though his 6,400 La Liga minutes and versatility have strengthened Arsenal’s rotation.
