Brentford have made an offer for Toulouse striker Thijs Dallinga.
L'Equipe says the Bees' bid of ‚¬18m has been rejected by the Ligue Une club.
Toulouse are seeking ‚¬35-40m to sell.
This season, Dallinga has ten goals and two assists in 26 games for Toulouse.
He made his debut for Holland last year, when he played half a game in the European Championship qualifier against Gibraltar.
