Lampard and fellow Chelsea legend Didier Drogba formed a brilliant partnership at Stamford Bridge and combined for a record 36 Premier League goals.
That record is under severe threat, however, with Kane and Son moving level with Manchester City heroes Sergio Aguero and David Silva and Arsenal greats Thierry Henry and Robert Pires with 29.
Kane and Son could add to their tally against Chelsea this weekend and Lampard is wary of the threat of Tottenham’s two star forwards.
‘They are certainly a threat to that record,’ Lampard said at his pre-match press conference.
‘They are going to beat that comfortably, with the way they’re going. Fair play, I’ve got no qualms about that.
‘It’s something me and Didier were proud of but this is football and it moves on. Players of that level will always test that. I’m aware of their threats.
‘You look at the numbers they’re producing, the link-up play, the understanding is clear. Fair play to them and the coach for how they play and work as a team.
‘It’s something we have to be aware of. It’s a big strength of theirs but it’s not their only strength, they’re a strong team around that in lots of different areas but we also have to try and nullify those threats and make the most of our strengths.
‘With players like Son and Kane, they’ve worked on that relationship for a good few years now.
‘We’re in the early stages of that so yes I would love for our players to get those relationships and have that level of talent.’
Chelsea face Jose Mourinho’s Tottenham sitting third in the Premier League table, two points behind current leaders Spurs.
Lampard will be able to call upon USA international Christian Pulisic this weekend, while summer signing Kai Havertz is also available.
