Arsenal have made first contact with the agent of Manchester United and Chelsea target Nemanja Matic, as they look to complete a January transfer for the Benfica midfielder, reports talkSPORT.
The Serbian international has been heavily linked with a move to the Premier League this month, after catching the eye with some scintillating performances for Jorge Jesus's side.
Gunners boss Arsene Wenger is keen to lure the 25-year-old to the Emirates Stadium, and has already held preliminary discussions with the player's representative Dejan Mitrovic.
Matic could return to England three years after he was sold by Chelsea as part of the deal that brought David Luiz to Stamford Bridge in January 2011.
After impressing at Estádio da Luz over the past three seasons, the former Blues star is now one of the most coveted midfielders in Europe, with Jose Mourinho also among his growing list of admirers.
Manchester United has also been mooted as a potential destination for the in-demand star, as David Moyes looks to strengthen his Old Trafford squad in the mid-season window.
