Newcastle have made an improved offer worth £40million for Yoane Wissa, talkSPORT understands.
The Magpies' bid includes a £35m fee plus £5m in potential add-ons, although Brentford's valuation remains in excess of £50m.

Wissa is pushing to leave the Bees and believes this could be his last chance to play Champions League football, having snubbed interest from Saudi Arabia.
The 28-year-old has been training alone and recently unfollowed Brentford on social media as the club continued to block a move to St James' Park.
Newcastle have already had one bid for Wissa rejected this summer, along with unsuccessful attempts to sign Joao Pedro and Benjamin Sesko, who joined Chelsea and Manchester United respectively.
The Congolese international was previously told he could leave for just £26m, but the club have reneged on that after losing Bryan Mbeumo to Manchester United.

Brentford recently signed Dango Ouattara from Bournemouth in a club-record £42m deal - but club sources claim he is viewed as the Mbeumo replacement.
It means another striker would need to be signed before the Bees consider a bid for Wissa.
Meanwhile, Newcastle are thought to see Wissa as a replacement for Callum Wilson, who left the club on a free transfer at the end of last season.
Therefore any deal with Brentford is unlikely to impact the future of Alexander Isak, who lashed out at Newcastle in a bombshell statement on Tuesday night.
Like Wissa, Isak wants to leave and believes his employers have broken promises over his future.
