That is according to ESPN FC pundit and former Major League Soccer star Alejandro Moreno.
Both Dembele and Malcom have seen their time on the pitch at Barcelona restricted in recent weeks.
Dembele started the first seven La Liga games of the season but has had to settle for appearances off the bench in the last four.
Malcom, however, is yet to start a league match since his summer move from Bordeaux.
The Brazilian’s only start came in the Copa Del Rey win over second-tier outfit C Leonesa.
Malcom has been linked with a move to Chelsea in a potential swap with Willian.
Dembele’s future at the Nou Camp was also in doubt in the summer after a difficult first season in La Liga.
But Moreno does not think it would be wise for either of them to force a move away yet.
A fan tweeted in to the ESPN FC Extra Time showing, writing: “Should Dembele or Malcom force a move in January?
“Chelsea should be all over these two.”
But Moreno claimed it was wishful thinking from the Chelsea supporter.
“Well maybe James Murphy is a Chelsea fan and wants the influx of Dembele and Malcom,” he responded.
“I don’t think that either one of them should force a move, nor will force a move.
“They’re fine at Barcelona.”
Malcom came on as a second-half substitute for Barcelona in their Champions League clash against Inter Milan on Tuesday, replacing Dembele.
The 21-year-old scored almost instantly but Mauro Icardi cancelled it out with a late equaliser in the 1-1 draw.
