NOTTINGHAM, Oct 19 — Mikel Arteta said Arsenal’s strength in depth will be key to their Premier League title defence after Noni Madueke came off the bench to clinch a 1-0 win against Nottingham Forest yesterday.

Arteta’s side were well below their best at the City Ground and did not register a shot on target until Madueke bagged their winner 10 minutes from full-time.

While the Gunners earned few style points in the East Midlands, they will not be overly concerned after moving within three points of leaders Manchester City.

Arteta is able to dip into one of the stronger substitutes’ benches in the top flight and he made full use of the resources at his disposal to turn the tide by the banks of the River Trent.
