Tottenham Hotspur manager Jose Mourinho believes Chelsea's lavish spending spree ahead of the 2020-21 season has raised the heat on manager Frank Lampard to deliver the Premier League title.
Chelsea spent more than £200 million ($266.08m) to bring in Edouard Mendy, Timo Werner and Kai Havertz among others, instantly making them contenders in Lampard's second year at the helm.
Mourinho, whose Premier League leaders face Chelsea on Sunday, said he had experienced similar pressure while managing title-winning teams at Chelsea, Real Madrid and Inter Milan.
"When you are favourites, you know why," Mourinho said, after overseeing training with Harry Kane, Heung-min Son and the other Spurs stars. "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."
Lampard, who won two Premier League titles and an FA Cup when he played for Chelsea under Mourinho between 2004-07, played down suggestions of a rift between him and his former coach.
"We've always had a good relationship," Lampard said.
"When we are managers of big clubs that are rivals, it does change the relationship. Not in a bad way - I've got no problem with him."
