Sky seem to think so, they reported an hour ago that Chelsea have made a £20M bid to bring Matic back to the bridge.
The midfielder made just two appearances before leaving in a part exchange deal for Luiz in 2011.
Blues boss Jose Mourinho sees Matic as the man to strengthen the centre of his midfield this January.
Matic was a big success in Portugal
Matic has been capped nine times by Serbia and the 25-year-old has been a huge success since making the switch to Benfica.
Some reports claim that he has a buy-out clause of around £37m in his current contract.
Expect it to be made official tomorrow.
