Arsenal are reportedly set to step up their interest in Benfica winger Andrija Zivkovic and will watch the 21-year-old in action against Porto on Sunday.
The Gunners have been following Zivkovic for some time and will sent scout Luis Boa Morte to Sunday's game as their interest intensifies, according to Portuguese newspaper Record (h/t Sport Witness).
Zivkovic has spent most of his career on the right flank but can also play in a more central role or even on the left. He's made just 12 league starts for Benfica this season but has three goals and three assists for Rui Vitoria's league leaders.
