Few England players will be feeling the heat as much as Wayne Rooney on the team's pre-World Cup stop in Miami.

The closer it gets to the World Cup, the greater the pressure on the striker to produce the kind of performances for England that earned him the most lucrative contract in Manchester United history last season.

Rooney, who collects more than $20 million a year at United, has scored 38 goals in 89 England appearances since bursting onto the scene as a teenager. But he has now gone four matches on international duty without a goal.
