The 21-year-old, who was signed from Bayer Leverkusen for £71 million earlier this month, made a low-key debut in the 3-1 win over Brighton last Monday.
Havertz was given a deeper midfield role against Brighton, but in the 2-0 loss to the Premier League champions at Stamford Bridge, the Germany international was played as a false nine with Timo Werner operating from a wider attacking position.
Speaking after the match on Sunday, former Liverpool defender Jamie Carragher suggested that Lampard could face an early headache in trying to find Havertz’s best position.
But Lampard is confident that Havertz will thrive once he adjusts to the Premier League.
Asked if it was always his plan to play Havertz as a false nine against Liverpool, Lampard told Chelsea TV: ‘It was the plan regardless, Timo likes to play off the left side.
‘He’s very versatile. He [Werner] can play centrally or left side, I think he was fantastic in moments today, you saw the difference he’s going to make.
‘With Kai, it was a feeling that he can be central and give them a problem by coming slightly deeper sometimes.
‘When he started to get into the game you could feel that a little bit.
‘He needs time, Kai Havertz. He trained just a few days before Brighton, again he’s had to recover and get ready for this game.
‘So I’ve got no doubt in time that we can be versatile with not just those two but the front players we have.’
