Arsene Wenger has criticised Lucas Perez for being too reliant on his left foot despite scoring his first Arsenal goals against Nottingham Forest.

The 28-year-old forward scored twice and assisted once as the Gunners completed a convincing 4-0 away win in the EFL Cup third-round tie on Tuesday.

The cup encounter was the his third in an Arsenal shirt since moving to the Emirates in the summer transfer window, and he scored two second-half goals, including a composed penalty.

Arsenal boss Wenger has identified Perez’s reluctancy to use his weaker foot as a concern but still praised the attacker for his contribution.

“He did well,” he said, as quoted by Sky Sports. “He’s quick, he’s determined. He uses well his left foot – a bit too much in my taste. He doesn’t use his right enough. Overall he’s like all the left-footed players, you know.

“But I like his second goal because he has shown not only technique but determination and fight for the ball and finishing and I like that. The part he played in the goal of [Alex] Oxlade-Chamberlain shows his awareness of other people and it is intelligent play.”

Perez has made two appearances in the Premier League against Southampton and Hull but is yet to complete a full 90 minutes in the competition.

The Spaniard is competing with team-mates Olivier Giroud and Alexis Sanchez for the starting position in attack.

He enjoyed a good goal scoring record at his former club Deportivo, scoring 24 goals and supplying 14 assists in just 59 appearances.

Arsenal host a crucial London derby against Chelsea on Saturday evening and will hope to continue their good start to the season, in which they have amassed 10 points from five games.

Perez will hope he is contention to start for the Premier League fixture following his brace.
