Lampard won two Premier League titles under Mourinho's Chelsea tutelage and now the duo will square up amid derby intensity at the Tottenham Hotspur Stadium.

"I would always have big respect for all my managers; if I was to text or ring a manager, I'd always call them boss or gaffer, even when long gone," said Lampard.

"But when you go up against someone like that, so influential, I knew it was different. It was a good honour to go up against him (for Derby against Manchester United last season), but I wanted to beat him.

"It would be strange to call him boss now. Now I am an ex-player, on this side of the fence, I won't be calling him boss.

"But that doesn't take away from the respect I have for him. And it's not the me and Jose show. It's a game against Tottenham.

"I want to beat him. I respect him and know what a top manager he is. He wants to beat me because he used to manage Chelsea, he used to manage me, and now he's managing Tottenham and wants to beat us."

Mourinho won three Premier League titles, one FA Cup and three League Cups across two spells as Chelsea boss.

The former Real Madrid and Manchester United boss knew Blues supporters would not look kindly on his Spurs switch, and Lampard knows the fans could voice discontent this weekend.

Asked if he expects Chelsea fans to make their point to Mourinho, Lampard said: "If you go to the fiercest rivals, the fans will give the answer. That doesn't mean they've forgotten the history or don't respect it.

"Jose Mourinho is a manager who wants to work. He took that opportunity.

"Jose Mourinho won't be too concerned about that, either. Look at the times he's come back with United; it did look like (he doesn't care).

"We know it's a huge rivalry (between Chelsea and Tottenham). Probably, in my era, it became the biggest of the London derbies.

"It felt like that in the stadia and on the pitch. So possibly it is.

"Any rivalry, any local derby, ups the ante slightly. I remember that feeling, that eagerness to win and desperation not to lose. That's how we all feel about it."

England strikers Tammy Abraham and Harry Kane will go head-to-head in Sunday's Spurs clash, with Lampard insisting Chelsea's hitman can have no better role model than his Tottenham counterpart.

"There's no better person for him (Abraham) to look up to in football than Harry Kane.

"Harry Kane is the all-round number nine, if not the best then close to being the best in the world. He should look up to that.

"I know he does, and is trying to take up the work ethic Harry has to try and be the best in the world.

"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."
