John Terry has tipped David Luiz to eventually take over his mantle as the Chelsea captain.
The Brazil international has made an instant impact at Stamford Bridge since his £22million arrival from Benfica in the January transfer window.
And Terry has praised the 24-year-old for the way he has settled in the English game.
The England skipper told the Daily Star: "David is incredible. To have such an impact at such an early stage of his career here is amazing.
"Normally, when a player first comes in it will take him at least three or four weeks to settle but David has come in and hit the ground running straight away.
"It's very different for him over here.
"He has played in Portugal with Benfica, so he is learning about our game all the time."
Terry, 30, who has been leading Chelsea for seven years, has lifted three league titles and three FA Cups since 2004, including a first-ever Double last season.
And he is convinced Luiz has all the characteristics to wear the armband one day, adding: "We are talking long-term here but, for me, with the quality he has, he is possibly a future captain of this football club.
"David is a great lad. He wants to learn and improve every day. That is something we will get to see the longer he is here."
