According to 'O Jogo', the young Benfica player could part ways with the Italian club next summer, if he is able to finalise exit negotiations with the Portuguese club.
Zivkovic, the Serbian midfielder, has a contract with the club lasting until 2021, a fact that will not be a impediment to either Arsenal or Manchester United, who are both interested in his signing.
Moreover, Zivkovic was watched by club scouts for Arsenal and Manchester United in the match against Porto last weekend. The club is aware that the two Premier League sides are keeping a close eye on the young midfielder.
This season, Zivkovic has featured 26 times for Benifca, scoring three goals and providing five assists.
