Chelsea forked out a mammoth £71m to secure the services of the highly-rated German until the summer of 2025.
Many will expect Havertz to hit the ground running in the Premier League given his huge transfer fee and his known credentials in the Bundesliga, but Lampard has admonished fans to wait till the Bayer Leverkusen academy graduate settles despite hailing the youngster as a fantastic and an exciting talent.
“Havertz is a really exciting signing for myself and for the club first and foremost,” the former Derby County manager told Chelsea’s website.
“He is a player I have been aware of for a long time and as a fellow attacking midfield player, I have paid particular attention to those type of players for some time.”
“I was aware of his talent and in conjunction with the club, we know how we want to go forward and look to improve in the right areas, and for players who are going to be here hopefully to improve and mature, but are already at a very high level, he absolutely fitted the bill for us, so I am delighted to have him.”
He added: “We also have to understand that he is a fantastic young talent but we must give him time to let him settle and let those talents come through.”
“So I think we will see him give everything that we want him to give in terms of goals and assists, and hopefully those numbers will go up, but we also must give him time. But in terms of his talent I think we are in for having a really exciting player coming into the club.”
