Benfica could be ready to swoop for Partizan Belgrade starlet Lazar Markovic, who had looked set for a move to Chelsea.
Chelsea have long been leading the chase for the brilliant young Serbian, who is reported to have revealed after the weekend derby with Red Star that he would be leaving this summer.
However, Benfica have now emerged as contenders for the 19-year-old's signature and he admits that he would be tempted by a switch to the Estadio da Luz.
"Benfica is a great club, one of the biggest in the world," he told Abola.
"I truly believe that it would be good for me to play for them."
Benfica have already agreed deals for two more Serbs in the shape of Miralem Sulejmani and Filip Djuricic.
Meanwhile, another player who could be heading to Benfica is Bayer Leverkusen's German youth international Christoph Kramer - who has spent the last two seasons on loan at Bochum.
Kramer's agent Gerd vom Bruch told Express: "Christoph Kramer has gone through two great years at Bochum. He deserves to have caught the eyes of clubs able to offer him a great future.
"He has some interesting enquiries. The enquiry from Benfica is the most concrete one, this club is extremely interested in him."
