Chelsea defender David Luiz has urged Frank Lampard to follow orders from manager Andre Villas-Boas.
The England international has often been overlooked this season, with Villas-Boas sparking a transition period at Stamford Bridge.
However, for the good of the squad, Luiz believes Lampard has to begin to respect the manager.
"No one has to be someone's father or son in a football club," he said.
"There are no privileged people there. He [Lampard] simply has to listen to the coach when he gives orders and take them.
"No player can forget that they are just an employee of the club."
The Blues have endured tough times this campaign, looking lily to fall short in the title race, while their attempts to qualify for the Champions League have also hit problems.
The form of last January's £50 million signing Fernando Torres has also undermined the club's season, with the Spaniard having failed to score since October.
Luiz's own form has come under scrutiny, with the Brazilian own prone to over elaborating in defence.
