Tottenham's performance this season is also a bit unstable. Tottenham won against City in the EFL Cup match. Tottenham won 4-1 against Aston Villa in the Premier League match. But they lost to Galatasaray in the Champions League match. Tottenham also lost to Ipswich Town in the last match. So it will be difficult for Tottenham to get points against City.
I wouldn't take into account the EFL Cup matches, because Guardiola gives the first team players a chance to rest in the cup matches and players from the bench often come out on the field, and especially since City are currently experiencing some kind of decline, so it's hard to set them as an example of a tough opponent. Tottenham are in tenth place after 11 rounds, so this season can be considered not very successful for them, but there is only a 3-point difference between them and Chelsea, who are in 3rd place, so the teams are very close.
