Manchester City midfielder Yaya Toure says the club's coaching staff have them primed ahead of facing Real Madrid.
City kickoff their Champions League campaign at Real this week.
Toure said: "I maintain contact with some ex-companions at Barca but I do not need their advice over Real.
"The City staff have prepared for this match in great detail and that's enough information for us. Our last campaign was a disaster and we want to change all that.
"To win in the Bernabeu is a unique experience, enough to put you on the front pages. We shall put in our maximum to achieve that.
"So we shall be concentrating hard from the very first second.
"For me, the key to the result means winning the midfield battles with Xabi Alonso, Mesut Ozil and Sami Khedira. This is the key for the match."
