Chelsea thrashed Everton 4-0 at Stamford Bridge, where they were without the injured N’Golo Kante and Mateo Kovacic and the suspended Jorginho.
Billy Gilmour retained his place in the team and was again impressive in Jorginho’s anchor role.
And Blues boss Lampard was delighted with the way Ross Barkley and goalscorer Mason Mount gave the teenager excellent protection despite their own attacking instincts.
Lampard admitted he felt playing with two attacking players in central midfield could be problematic if they neglected the defensive side of their game.
He therefore spoke to them about the potential pitfalls – and their response was emphatic.
Lampard said: “I’m not trying to be anyone, but you look at how Man City have played it and they have offensive number eights who want to work off the ball.
“I’m not going to lie and say I didn’t have, not concerns, but you’re very aware when you have two players that could easily be number 10s and they have a lot more work to do off the ball.
“What I do know is that they’ve got the capacity for it. It was more: ‘Can you be focused and use your energy, maybe not so much all the time to be going forward, but to use it slightly backwards and also be aware that you need to protect Billy when the ball’s on the other side?’
“We had those talks and I think that was probably one of the most pleasing parts of the performance for me – they gave us that (defensive work) but also when we get the ball we’ve got two really offensive players. “I thought the players in the midfield got that balance right on the pitch.”
