Lampard is adamant he had the right system in place for the 4-0 rout.
He said, "We have different ways we can play even within games. It needs to be changeable, it needs work on the training ground and it needs buy-in from the players.
"The reason we lost the game against Manchester United was not because of where our line was on the pitch, it was because of individual mistakes in turning the ball over and not following a runner at the right time. Those are the little details that you have to be on top of constantly. We reflect on it, we watch the videos back and we look to improve."
