The new Barca boss was asked about his countryman, who appears to be close to moving to Camp Nou.
Ronald Koeman said Barcelona must sell before they can think about signing Lyon captain Memphis Depay as the head coach expects to start the La Liga season with no additions to the squad.
Depay has been tipped to reunite with former Netherlands coach Koeman at Barca following his exploits for Ligue 1 outfit and Champions League semi-finalists Lyon.
However, Lyon president Jean-Michel Aulas – prior to Tuesday’s 2-1 loss against Montpellier – claimed Barca cannot afford to buy Depay due to their finances amid the coronavirus crisis.
Koeman, who has replaced Quique Setien at Camp Nou, was asked about former Manchester United forward Depay amid talk of a €25 million (£23m/$30m) transfer and he told Fox Sports Netherlands: “For Depay to arrive, you must first sell.”
