The new Blues boss has reportedly told outcasts Tiemoue Bakayoko and Danny Drinkwater that they are surplus to requirements.
Both midfielders have failed to make the grade at Stamford Bridge since arriving in the summer of 2017.
While Bakayoko spent last season on loan at AC Milan, Drinkwater was frozen out entirely by previous manager Maurizio Sarri.
Both midfielders were given chances to impress on Chelsea’s pre-season tours of Ireland and Japan.
Lampard assessed their credentials and analysed their prospects of being involved with his squad next season
And his conclusion was the the duo – who cost a combined £75m – will not be part of his plans for the new campaign
Bakayoko, 24, failed to establish himself at Stamford Bridge after his £40m move from Monaco two years ago.
After a disastrous first season, in which he was booed by his own fans, the Frenchman was farmed out on loan to the San Siro.
He found some form at Milan, making 42 appearances and sparking talk that the club might be interested in signing him permanently.
But Rossoneri boss Gennaro Gattuso was sacked and talk of a deal has since diminished.
Chelsea will also take a huge financial hit on Leicester title-winner Drinkwater.
The central midfielder has made next to no impact since his £35m move from the King Power Stadium, playing just 24 games in two years.
He was recently lampooned on social media because of his surname in reference to Thursday’s heatwave
And Drinkwater himself got in on the act, writing on Instagram: “Today is supposed to be the hottest day of the year in the uk… remember, stay hydrated. #drinkwater #ukheatwave #hothothot”
According to lampard is committed to giving more game time to younger stars such as Ruben Loftus-Cheek.
