Everton have had the edge on Manchester City ever since Joleon Lescott's controversial move to Eastlands.
The move enraged Toffees fans so much, clashes between the teams have turned into needle matches.
And for all of City's cash, it is Everton who have had the better of it, winning nine of the last 13 league games - with Cahill himself scoring FIVE times.
Cahill said: "We concentrate on giving players long contracts and have a good core who love the club and would run through brick walls for it. The spirit of this team is the thing."
