Budding Serbian midfielder Andrija Živković is drawing interest from Chelsea and Valencia among other clubs according to his agent although a report said Benfica already agreed to terms with the rising star.

The 18-year-old has been breaking records as listed by the International Business Times becoming Partizan's youngest captain (17 years old) and was Serbia's youngest representative.

Živković also had a stellar performance for the Serbs in the Under-20 World Cup in New Zealand assisting teammate and fellow midfielder Nemanja Maksimović for a 1-0 victory over Brazil to win the tournament.

Reports say Živković, who is represented by agents Pedja Djordjevic and Pini Zahavi, still has one year remaining in his pact with Partizan.

Benfica was linked closely to Živković before the World Cup but in a statement shared with O Jogo, Djordjevic said they are looking at their options as Chelsea and Valencia express interests, ESPN reported.

"[Our aim] is to analyse all the options we have, and decide calmly. Valencia and Chelsea are two of the clubs who are interested in Živković," Djordjevic said.

Spanish newspaper Super Deporte reported that signing Živković is a priority for Valencia owner Peter Lim and Portuguese super-agent Jorge Mendes.

Along with interest in signing Živković, ESPN reported that Valencia is also close to a deal acquiring Deportivo Maldonado goalkeeper Gerónimo Rulli who played remarkably for Real Sociedad last season via loan.

The 23-year-old's performance with Real Sociedad earned him his first call-up for Argentina, ESPN added.

Valencia looks at Rulli as Diego Alves' replacement since the 29-year-old has been plagued by injury, although Rulli already expressed last May his desire of staying with Real Sociedad.

Meanwhile, Super Deporte also reported Chelsea manager José Mourinho's admiration for Živković.

But despite Chelse and Valencia's interests, Eurosport.com said a report stated that Benfica offered Živković a five-year deal and both sides already agreed to terms.
