Brentford must go higher to land Fiorentina attacker Nico Gonzalez.
The Argentina international attracted a €40m bid from the Bees last year, which Fiorentina threw out.
La Gazzetta dello Sport says the Viola management see Gonzalez as a key player for their future plans.
However, they are prepared to sell for at least €50m this summer.
It's yet to be seen if the Bees will return with a new offer this summer.
