Why Nadal will be such a threat at Wimbledon

> Hunger: Nadal has recovered from a seven-month injury lay-off to look as strong as ever on clay courts. Now grass awaits, and his appetite for success looks as great as ever.

> Form: Nadal has won seven of the nine tournaments he has entered since returning to the tour in February, a startling record.

> Athleticism: At 6ft 1in, the muscular Spaniard has a remarkable physique for tennis. His mobility has been apparently unaffected by last year's injury, and his strength, speed and reach mean he returns shots that many cannot get near.

> That forehand: Nadal's lethal whipped forehand, when combined with his zip around the court, serves as an invaluable asset, allowing him to generate fierce top-spin. Both a vital attacking and defensive tool, it gives Nadal the edge more often than not.
