Arsenal interim manager Freddie Ljungberg has revealed that he started Gabriel Martinelli ahead of Alexandre Lacazette due to the Brazilian's energy levels.
The Gunners broke a run of nine games without victory as they came back from one goal down to beat West Ham United 3-1.
Martinelli was handed his first Premier League start in the West Ham clash at the expense of Lacazette and grabbed the opportunity with both hands as he scored the leveler.
In an interview with BBC, Ljungberg revealed why he dropped Lacazette for Martinelli, "Martinelli did amazingly. He is like a Duracell battery, he keeps going.
"Laca (Lacazette) is a tremendous player but I had to make a tough decision. Gabby is a fantastic player. He’s very, very young but he has that energy about him so he goes and goes.
"He has no fear, he just keeps going. It’s a pleasure to see him on the pitch and for him to have success today brings a smile to your face."'
The Brazilian had scored six goals in all competitions before his debut league goal against West Ham.
