England boss Fabio Capello admits injuries to key players are beginning to concern him.

Chelsea left-back Ashley Cole his currently recovering from surgery for a broken ankle.

David Beckham will miss the World Cup because of an Achilles injury, Tottenham pair Jermain Defoe and Aaron Lennon are currently sidelined, and there are ongoing concerns about the fitness of Portsmouth goalkeeper David James and captain Rio Ferdinand, the Manchester United defender.

It is an anxious time for Italian Capello who knows he has to have his players at their peak - physically and mentally - if they are to have a chance of triumphing in South Africa.

Capello told CNN: "I have big confidence in my team. If all the players will be fit and all arrive physically in good condition and in a good moment we can win the World Cup. We are one of the best teams in the world.

"Sometimes you have to be lucky to beat some teams because there are refereeing mistakes, bad luck, post in, post out, this is football."
