The Chilean boss has complimented Pochettino for creating such a strong squad at Spurs, and says that his side will need to perform at their best if they are to leave north London with anything to show for their efforts.
“Every game is different, we are just believing that if we don’t play well we won’t win,” Pellegrini said.
“I don’t analyse Spurs’ start – they have good players, a very young team – so I think that Pochettino is doing very good work there and we’ll see how they do at the end of the season.”
City have been in fabulous form in the Premier League so far this season, but they did lose their last match in the league to West Ham United.
The Hammers countered on City with great success, and the defeat has allowed some of the teams chasing Pellegrini's men at the top of the table to make up ground.
It means that they will be keen to bounce back on Saturday, but beating Spurs has proved a tough objective for any side this term.
The Lilywhites have not lost in the league since suffering an opening day defeat to Manchester United, and they will be looking to keep their unbeaten run going as they strive to make their way up the Premier League standings.
