Arsene Wenger was pleased to see Lucas Perez score his first goals for Arsenal, although he feels the Spanish forward is too reliant on his left foot.
Perez made his second start for the Gunners in their 4-0 EFL Cup win at Nottingham Forest and was disappointingly peripheral for the first hour before he got his chance from the penalty spot.
With the Gunners leading through Granit Xhaka's 30-yard strike, Chuba Akpom went down under a challenge from former Chelsea defender Michael Mancienne and Perez tucked away the resulting spot-kick.
The 28-year-old then ploughed his way through the Forest defence and around the goalkeeper to prod in the third goal.
