Rodgers claims the feel-good factor will only last so long for Lampard, 41, in the cut-throat world of football management.
He said: “When I was at Chelsea, the guys would talk about it. If you've been a top player and walked into the changing room, you'll have that respect automatically.
“But after a few weeks, the same players will look at you and say, 'What are you going to do for me?'
“That's how the game works. Look at Zinedine Zidane at Real Madrid — he tries to get the strength of players.
“If you see your job as developing players, improving them to be the best they can, then you can have a successful career.
“No matter what background you come from, you have to have that respect and improve players. I admire the guys who want to come out of that arena as a player.
“It's totally different when you're a player. You're really focused on yourself — your diet, nutrition, you are self-employed.
“To go into management, you've got to look after everyone. There are examples of players who do make it — others that don't quite make it."
