LEFT BACK: Junior Diaz, Costa Rica
Who would have thought that tiny Costa Rica would get through a group containing Uruguay, Italy and England -- and concede just one goal in the process? The whole Costa Rica defense deserves credit but the experienced Diaz gets the nod as he has complemented the attack, setting up Bryan Ruiz's qualification-clinching goal against Italy with a superb cross from the left wing.
CENTER BACK: Rafael Marquez, Mexico
He has lost his long-time ponytail but the 35-year-old Marquez has retained the technical, positional and organizational skills that have helped guide Mexico into the last 16. Scored one of the goals in the 3-1 win over Mexico and his qualities don't appear to have diminished with age.
