Werner, a summer signing of 53 million pounds, has yet to score in the Premier League in the first three games.
While Havertz, 21, has struggled to prove why The Blues paid Bayer Leverkusen 70 million pounds for his services.
After pitching Werner, 24, in the first two games, Lampard cornered him from the left in the 3–3 draw with West Brom with Tammy Abraham at the helm.
Similarly, Havertz asked to deviate widely from his favorite role at number 10 in the camp.
Before Saturday’s clash with Crystal Palace, Lampard said, “Timo and Kai don’t necessarily have privileged positions themselves, yet I have a transparent concept of where I need them to play. “
“At the moment, injuries have not made it imaginable and rarely do we have to adapt in those difficult times.
Christian Pulisic remains one of those who has occupied the remedy table since the start of the campaign.
The American suffered a ham- tendon injury in the FA Cup final in August.
But Lampard admitted the winger back to the squad and could show up this weekend.
He added: “Pulisic is in the for tomorrow.
“I may not start the game because of the injury you received and it’s a complicated injury, but I’m very willing to get you back there.
“It’s wonderful to place it for itself and for the taste it gives the team, because it’s a vital player for us.
“Hakim Ziyech is getting close, but it doesn’t have enough compatibility to be on the bench.
“It is a great fault for us that have compatibility at this level of the season.
“Christian has been here for a year, so he doesn’t have that sleeping procedure that component of his debut last year.
“Hakim will bring us something absolutely different and I think they will help complement the offensive players that we have because we will have to be able to use other players during the season. I’m so excited to have you. Array “
