Freddie Ljungberg has said that Gabriel Martinelli is "like a Duracell battery" after the young forward helped to haul Arsenal to victory against West Ham on Monday.
The Gunners arrived at London Stadium on the back of nine games without a win in all competitions. In horrible form and low on confidence, they conceded a header from Angelo Ogbonna after 38 minutes.
Martinelli helped to inspire a second-half comeback, however, after sprinting onto a neat ball from Sead Kolasinac and slotting low into the back of the net. That was followed by goals from Nicolas Pepe and Pierre-Emerick Aubameyang, all within the space of nine minutes, which saw Arsenal run out 3-1 winners.
