Luis Suarez says Philippe Coutinho is ambitious enough to want to move to Barcelona.
Suarez played with the Brazil international at Liverpool during the 2013/14 season and has spoken of his admiration for his former team-mate's ability.
After failing to sign Coutinho last summer, Barcelona are thought to be planning a new effort to bring the Liverpool midfielder to the Nou Camp in the January transfer window.
Asked if Coutinho would want to sign for Barcelona, Suarez told Mundo Deportivo: "Obviously he must have because he's a player who has ambition and any player would want to come to Barca.
"I know him as a person and as a player because I played with him, but everyone knows what Coutinho can contribute.
"He is a footballer, who today, plays at a very high level."
Coutinho missed six of Liverpool's opening games of the Premier League season as speculation surrounding a possible transfer intensified.
The Catalan club failed with multiple offers for Coutinho despite the player wanting the move to happen and Suarez has praised the 25-year-old's attitude since his return to the Liverpool side.
"He went through a difficult and very complicated moment but as a professional he continued to show how good a player he is and the personal quality he has," Suarez said.
"Despite trying to leave Liverpool he continued helping the team and working. He is demonstrating as a professional who has the ambition to take a step further."
