Benfica midfielder Nemenja Matic is poised to rejoin Chelsea in a 26 million euro (£22 million) deal, according to reports in Portugal on Tuesday.
The Serbian international first signed for Chelsea from Slovakian side Kosice in 2009 but was sold to Benfica in the 2011 January transfer window in a deal which saw David Luiz move to Stamford Bridge.
Confirming the Chelsea interest Matic told A Bola sports daily: "Now is a good time to leave. I want to improve, I want to play in a better league and I want to go to Chelsea."
The paper says Matic will travel to London on Tuesday to finalise the deal
