Former Arsenal centre forward Paul Mariner says the Gunners need a world class striker if they are to be competitive next season.
The 62-year-old believes that striker Olivier Giroud will not lead the Gunners to glory and that Paris Saint-Germain's Edinson Cavani would be perfect for Arsenal.
"I don't want to see him [Jackson Martinez] at Arsenal in the coming year," Mariner is quoted as saying by Squawka.
"Cavani [yes]. With the side that they've got in the present moment, you can see the creators they've got in there.
"The likes of Giroud, for me, he doesn't do enough. He's not the answer to A. take them to the Premier League, and B. further in the Champions League."
In April, Thierry Henry also voiced his concern over the lack of firepower in the Arsenal attack.
"Arsenal need to buy four players, they need that spine," the Frenchman told Sky Sports.
"They need a goalkeeper, they still need a centre-back, they still need a holding midfielder and, I'm afraid, they need a top, top-quality striker in order to win this league again."
