Frank Lampard insists he will not be calling Jose Mourinho "boss" in Sunday's London derby at Tottenham.

Chelsea chief Lampard revealed he still refers to the bulk of his former managers as boss out of respect, but conceded he cannot use that term for his Tottenham counterpart.

Former England midfielder Lampard explained he still holds his former Chelsea manager in the highest regard, but must treat the Portuguese as both equal and rival this weekend.

"He will be different, but he can go really, really far following that kind of model."

Asked if Kane shows similar traits to him in his playing days, Lampard added: "Yes, from the outside, he does remind me of myself. He's maximised every bit of his talent, or is maximising it.

"He's a driven boy, family man, wants to work and eke every bit out of his career. I have huge respect for him. We'll be rivals on Sunday, but we have huge respect for him."
