Koeman is currently assembling his new look Barca team, with several departures expected at the Nou Camp.
Coming in though, it’s thought the former Everton boss is eyeing a move for Wijnaldum, having coached the Dutchman with Holland.
Koeman is clearly a big fan of the ex-Newcastle man’s talents too, describing him as versatile in the midfield, and an excellent team player.
“First of all, he plays for a great team at a high level,” he said. “He is also more experienced that he was a couple of years ago.
“He is a so-called multi-functional midfielder. His best position is to play as an attacking midfielder, but at Liverpool he’s shown he’s able to play as a controlling midfielder.
“He’s a team player as well. He’s not someone who thinks he is more important than the team.
“He always tries to make other players better. He is a great player to work with.
“He’s had a difficult time in the Dutch national team — now he is ready to reach his level at Liverpool.”
Despite being a key man under Jurgen Klopp during their huge success, Wijnaldum is yet to secure his long-term future at Liverpool.
And the German will be hoping talk of a move to Catalonia won’t persuade him to seek a way out at Anfield.

Klopp will take some comfort in the fact that Barcelona will have to pay a £100m premium on any players they sign from Liverpool.
The extra cash comes thanks to some incredibly astute business from sporting director, Michael Edwards, who inserted the clause while negotiating the £142m sale of Philippe Coutinho in 2018.
