Toney will sign a five year contract at Championship side Brentford tomorrow (September 1). The fee is officially undisclosed, but is thought to be more than the previous club record Posh sale of Dwight Gayle to Crystal Palace for £6 million in July, 2013.
Here we look at how the other 10 million-pound Posh men fared...
.
DWIGHT GAYLE: £6 million to Crystal Palace, July, 2013. Posh signed this gifted striker from Dagenham & Redbridge for £500k just seven months before they sold him for a profit of £5.5 million. Palace had just been promoted to the Premier League when he joined them, but he made more sub appearances (40) than starting appearances (34) in three seasons at Selhurst Park before moving to Newcastle for a reported £10 million. He helped Newcastle to promotion to the Premier League in the 2016-17 season with a 23-goal campaign and he remains at St James Park although he is currently out of action with a serious knee injury. Enjoyed a successful spell with West Brom on loan in the Championship and is seen as a second tier goalscoring expert. POST-POSH VERDICT: A strong career. Photo: Midlands

BRITT ASSOMBALONGA: £5.5 million to Nottingham Forest, August 2014. Posh cashed in on this striker after just one season at London Road. The profit was a cool £4.25 million. He was a big hit at Forest with 30 goals in 69 appearances (50 starts), but the Midlanders couldn't resist a £15 million bid from Middlesbrough in July 2017. Assombalonga has been at the Riverside for three seasons now scoring a creditable 42 goals in 129 appearances (95 starts) for a team who have not been successful. POST-POSH VERDICT: The boy's done well enough. Photo: Midlands

JACK MARRIOTT: £4 million to Derby, July 2018. Yet another one-season wonder for Posh and yet another impressive profit (Posh paid Luton £400k for him). Frank Lampard signed him for Derby, but after a decent first season with the Rams he has struggled because of injuries and a change in manager/approach. Marriott has 16 goals in 80 appearances for Derby so far., but he's started just 37 games. POST-POSH VERDICT: A struggle of late. Photo: Midlands

RYAN BENNETT £3.5 million to Norwich City, January, 2012. The only defender in this list, but what a classy performer he was at Posh. And he took the step up in standard in his stride by helping both Norwich City and Wolves into the Premier League where he performed with credit for both clubs. Spent the end of last season on loan at Leicester City. POST-POSH VERDICT: Outstanding. Photo: Midlands
