The 31-year-old newly-installed vice-captain also rejected suggestions that striker Wayne Rooney might be easily provoked into hot-headed retaliation when England play the United States in their opening group C fixture on Saturday (June 12).

Rooney was sent off for retaliation, stamping on Portugal defender Ricardo Carvalho, in his last finals appearance in the quarter-finals four years ago.
Lampard, however, believes the fully-committed and energetic 24-year-old striker has matured sufficiently in the time since that dismissal to be able to rise above any deliberate attempts to prompt a red card.

Wilkins had taken over as captain only minutes before when Bryan Robson went off with a dislocated shoulder and his dismissal marked a sad finale to his World Cup career with England who reshuffled their team and went on to reach the quarter-finals where they were eliminated by Argentina, the eventual champions.
Beckham's dismissal deprived England of a key player and they lost the match against Argentina on penalties after an exhausting 120-minutes battle to reach the last eight.
Rooney's red card was similarly costly as the remaining ten men struggled through extra-time again before losing on penalties to t
