Despite Manchester City's flying start to the Premier League season, Manuel Pellegrini believes it will be tough for his side to take all three points at Everton on Sunday.
Pellegrini's men have laid down an early marker as they seek to regain the Premier League title surrendered to Chelsea last season.
And, with similar tactics likely on Roberto Martinez's mind, Pellegrini is under no illusions as to the task City will face on Merseyside.
"It will be a difficult challenge, they are a difficult team who play very good football," Pellegrini said.
"They didn't play well against Watford but scored two goals, and in their second game they played very well and scored three goals.
"We must be very concentrated and play with a lot of intensity to win there. They try to have good possession of the ball, I'm sure we will see a similar Everton as to previous seasons."
Everton have been boosted by Aiden McGeady's recovery from a hamstring problem.
Martinez credited a fine team showing after overseeing success at Southampton, rather than Romelu Lukaku's double, and feels a similarly well-rounded display will be needed against City.
"When you perform as a team, you are always going to see certain individuals with enormous talent shining," Martinez said. "But the key is to perform well as a team.
"It is the same with Sunday – if we rely on one or two individuals, we are going to fall short. Against City it will be the same as Southampton. We will have to be very good in everything.
"If you are not very strong throughout every aspect of the performance, you will find playing against Manchester City very tough."
