The Spanish centre-back - on loan from Flamengo - made his debut during Monday night's FA Cup win at Portsmouth
Martin Keown believes Pablo Mari must be given more opportunities following his impressive Arsenal debut.
The Spanish centre-back was handed his first Gunners start on Monday night and produced a encouraging showing as Mikel Arteta’s side booked their spot in the FA Cup quarter-finals with a 2-0 win at Portsmouth.
Keown was at Fratton Park on the night and watched on as Mari formed a strong partnership with David Luiz at the heart of the visitors’ defence.
