Spurs have lost 3-0 against Manchester United while Manchester City managed to beat Spurs 5-1 in North London.
“We played two big teams for our first two matches in the Premier League,” Kaboul told L’Equipe.
“It was very difficult, above all the last match against City. I even found City more impressive than Manchester United. I felt more difficulties against them at home than I did at Old Trafford.
“City can be a great success. I could even imagine them achieving the same run as Arsenal, when the Gunners were champions and remained undefeated all season long.
“Indeed, I could bet some money on that team for the title.”
