Matt Besler and Omar Gonzalez are fast-becoming a vital duo within the USA national team.
26-year old Sporting Kansas City star Besler and 24-year old LA Galaxy ace Gonzalez have started five games together in central defence which has included three clean sheets in 2014 World Cup qualifying.
"Before every game we always give each other a few things to work on and make sure we do right," Gonzalez told USsoccer.com.
"With each game, you need to say less and less just because you know what to expect from each other. The chemistry is definitely building, and hopefully we can put out some more shutouts because that's what we're on the field for."
Besler added: "Omar and I are talking to each other constantly throughout the game and that definitely helps us. I think we complement each other well, we both believe in each other. The key to the central defender partnership is being together, being on the same page."
