Dembele, 23, was close to joining Manchester United late in the summer transfer window, but a deal was not concluded.
It has become clear that Dembele is not a big part of Ronald Koeman’s plans for the future.
In Barca’s first three La Liga games, Dembele has played just 20 minutes as a substitute against Villarreal.
Koeman gave the go-ahead for Dembele to be sold in the summer, with Memphis Depay lined up to replace him.
Dembele is now considered a transferable player, especially since his contract expires in June 2022.
In the coming weeks, Barcelona will hold a meeting with Dembele’s representatives to discuss his future.
Club officials will make it clear that if Dembele does not extend his contract, he will be placed on the transfer market.
Barca want Dembele to extend his contract to avoid the risk of losing him for free.
The Catalan club paid more than €100m for Dembele, but given his contract situation, would be willing to accept just over €50m in January.
There is a belief within Barcelona that Premier League clubs could make offers for the speedy winger.
Dembele’s departure would allow Koeman to bring in the two players – Depay and Eric Garcia – he believes will complete his squad.
Both Depay and Garcia are out of contract next summer and could be signed in cut-price deals in January.
