Chelsea could make a transfer swoop for John Stones this summer after the Man City defender fell further down the pecking order following the arrival of Nathan Ake.
Stones joined City four years ago in a £50m deal from Everton but last season featured just 16 times in the Premier League.
Pep Guardiola is also thought to be keen to bring in further defensive reinforcements, which could include Napoli’s Kalidou Koulibaly.
That has sparked interest from Stamford Bridge boss Lampard who feels he can resurrect the central defender’s career.
The centre-back may seek a move to resurrect his career elsewhere and Chelsea could be the ideal place.
Stones could find himself out of contention for a place in Gareth Southgate’s England team if he continues to sit on the bench at City.
A move away with more regular first-team football could help him cement a place for next year’s European Championships.
