The 24-year-old Serbia international has been heavily linked with a move back to the Premier League after a series of scintillating performances at Estadio da Luz over the past two seasons.
Matic arrived at Stamford Bridge in a £1.5million deal from Kosice in 2009, but made just two first-team appearances for Chelsea, before joining Benfica as part of the deal that saw David Luiz move to west London in 2011.
He also spent a period on loan in Holland with Vitesse Arnhem, but has excelled so much in the Primeira Liga since that Jose Mourinho is keen to re-sign him for Chelsea this summer.
Manchester United have also been credited with an interest in bringing the midfielder to Old Trafford, as new manager David Moyes begins making transfer plans of his own ahead of the 2013/14 campaign.
Matic admits he is flattered to be mentioned in the same breath as the likes of Manchester United and Chelsea - and particularly Mourinho - but reiterated his commitment to Benfica for the foreseeable future.
"Frankly, I want to stay another year in Lisbon," he said. "Of course, someone like Jose Mourinho wanting me to go back to London would be an opportunity to prove that I can play in the Premier League.
"But I want to achieve more at Benfica, particularly in the big games."
After missing out on the domestic title to rivals Porto, and being defeated in both the Portuguese Cup final and the Europa League final in the final weeks of last season, Matic wants to progress further in the Champions League with Benfica next year.
