How do you take team management and leadership into consideration to get into a big negotiation?

During negotiations, it is a plus factor when clients come to know that you are not alone to decide on matters but have a team to depend. As the old "adage"- two heads are better than one, it clearly shows your client that all critical decision making is discussed to your team before making a decision. And being a team leader means you have the ability to lead the team in all aspects of the negotiations or dealing with critical decision making. Clients upon knowing these things will surely be impressed and will have confidence with dealing with you.
