Gabriel Martinelli has hit back at his detractors and insisted "I know what I can do" after his place in Brazil's World Cup squad was labelled a "joke" by former Selecao star Neto.
The Arsenal forward has enjoyed a positive season with the Gunners and is just one goal shy of equalling his best-ever league return, with five to his name already. Despite this, his place in the Brazil side for the upcoming tournament in Qatar has been called into question by an ex-international.
Martinelli has featured just three times for his country so far, without a goal in any of his appearances. However, he did play a vital role in the Brazil Under-23 side which secured a gold medal at the Olympic Games held in Tokyo last year.
