Mourinho has deployed his latest bout of mind games towards Chelsea, saying he no longer has to worry about pressure being the Spurs coach.
Chelsea became the first English side to spend £230million in a single transfer window this year, an outlay that followed a transfer ban and the sale of Eden Hazard to Real Madrid in a deal worth up to £150m in the previous summer.
Mourinho said he knows how it feels to work under great expectations, after two spells with Roman Abramovich and top jobs at Manchester United, Real Madrid and Inter Milan.
Mourinho said ahead of Sunday showdown: “When you are favourites, you know why you are favourites.
“And you have to accept that and you have to deal with that kind of pressure and responsibility. I was at clubs which were, let’s say, champions in the market because of their powerful investments.”
“I had to deal with that pressure. So now it’s not for me to deal with that pressure. It’s for others to deal with that pressure. That’s not for us.”
Lampard responded to Mourinho by saying: “If you look at the spending over the last couple of seasons, what Tottenham did in the summer I came to Chelsea and what they’ve done in this break, compared to us, you will see it has been very similar.
“The only thing that will get you success is hard work. The pressures are huge anyway. The pressures at Tottenham will be big, because Jose built a fantastic squad and has incredible players.
“It’s very comparable if you look at the spending for sure, since I have been at the club.”
Mourinho, however, insisted: ‘I’ve been at Chelsea and I know the difference. I enjoyed this first market with Tottenham.
“I enjoyed the kind of wise market where with less money you try to give a good balance to the team, not to make mistakes, choose the right guys. And I am really happy with what we got. Every one of them is answering well and giving his best.”
