Brentford rejected two approaches from Bournemouth on transfer deadline day for Chris Mepham.
West London Sport recently revealed that the Cherries were interested in the Hammersmith-born defender.
The two clubs held discussions on Wednesday and Bournemouth were first willing to pay around £5.5m for Mepham.
They then came in with a second offer, of £6.5m plus add-ons, but this too was turned down.
It is understood Bournemouth will not increase their bid any further.
The Premier League club watched Mepham play for the Bees’ B team and have continued to show an interest since his promotion to the senior side. Cherries boss Eddie Howe recently saw him in action at Griffin Park.
The Wales Under-21 international signed a new long-term contract in September.
He was on Chelsea’s books prior to joining Brentford at the age of 14.
