Arsenal are monitoring the progress of Benfica winger Andrija Zivkovic.
Portuguese media outlet O Jogo have claimed the Gunners sent a team of scouts to watch the 21-year-old during Benfica’s 5-1 victory over Rio Ave on Saturday.
The Serbian international, who has a £52.5 million release clause in his contract, has also been watched by Manchester United over the past few months.
Zivkovic progressed through the Partizan Belgrade youth system, before making his senior debut in April 2013.
He signed his first professional contract with Partizan in August that year and went on to captain the club the following April.
