The Blues splashed out a combined fee of around £117million to sign the two Germany internationals as part of the club’s extraordinary recruitment drive in the last transfer window.
Though Werner has netted eight goals in his first 17 Chelsea games in all competitions, the striker has been guilty of squandering multiple scoring opportunities.
The 24-year-old stunningly missed an open goal from one yard out in Saturday’s 3-1 win over Leeds United.
‘I’ve got no worries about Timo,’ the English boss said.
‘I think he’s come into this league, he’s made a big impact straight away. His speed, his direct nature, things he’s creating for the team, the fact he’s getting lots of chances, he makes lots of chances through his explosive nature and his eye to be in the right areas.
‘And that I love. I’ve got no worries about him. Timo’s going to be a huge player for this club.
‘He’s scored some goals already. Of course he’ll want to score more and he’s missed a couple but keep getting there and he’ll score those goals.
‘So I just think it’s a small moment as all strikers have and I have no worries.’
Meanwhile, despite a few flashes of brilliance, Havertz is also still finding his feet in English football after his mega-money move from Bayer Leverkusen.
The 21-year-old had a further setback when he tested positive for coronavirus at the beginning of November.
Lampard revealed that the midfielder struggled with strong symptoms of Covid-19, but similarly to Werner, he has huge belief in Havertz’s potential.
‘He’s fitting in really well,’ Lampard added.
‘He had really strong symptoms of Covid, he was very ill and struggling for quite a while. Some of the players have had it like that, some have been symptom free so we had to factor that in and that’s why it took two or so weeks before he was starting again once he returned from Covid.
‘He was playing in the No.8 role, the advanced midfield role, and I was delighted for him because you could see he was enjoying it and then obviously Covid cut that short.
‘Long-term, I’ve got absolutely no worries about Kai – in fact it’s the opposite. I know he’s going to be a huge player for this football club, in the Premier League.
‘He has all the attributes, all the personality, all the attitude and he’s going to be an absolutely top-class player for me, in the Premier League and in the world.
‘That’s how highly I rate him. There are very quick reactions sometimes to how people analyse new signings with price tags etcetera.
‘I think we have to understand that some of the best players to have graced the Premier League found it hard to get used to it and I think Kai has actually been very good and Covid has made it difficult for him.’
