The lightning winger made his World Cup debut for England in earning his second full cap as he entered the fray alongside Wayne Rooney just before the hour mark with the score at 0-0 and England struggling to break Trinidad & Tobago down in Nuremberg.

"Beckham did very well as a right-back. He put crosses flying in."
Aaron Lennon appears to have made the right impression on Sven Goran Eriksson after his display off the bench against Trinidad & Tobago.
