Brentford manager Thomas Frank admitted the club are not ruling out the sale of Said Benrahma.
The attacker showed his quality in the Carabao Cup with a stunning brace against Fulham.
In a game against a team one division above them, Brentford showed they could be knocking on the promotion door this season.
But Benrahma may get to the Premier League even faster if a club makes a big money bid for him.
"Am I confident he will stay? I'm confident that I would love him to stay," said Brentford boss Frank told reporters.
"But I don't know. Honestly, if the price is right we are open to selling, but if not we will be happy for him to stay.
"Either we are going to get a top price or we are going to keep one of the best players in the Championship. Has he added a few million to his price? 100%."
