There is no doubt which way Broad's career is heading. Having nailed down a place in England's one-day side over the past year, he came though a daunting Test debut on a flat pitch in Colombo six months ago and then grabbed his chance when the selectors decided it was time for a change of direction in New Zealand.
Matthew Hoggard and Steve Harmison were both dropped at Wellington, leaving Broad and Jimmy Anderson to join Ryan Sidebottom in an attack which has now been unchanged for five matches.
Now, as was the case a couple of months ago, Andrew Flintoff is fighting to get back in the frame following a long battle against injury. But although Broad is the junior member of England's pace trio, don't bank on him being the bowler to make way if and when 'Freddie' returns later this summer.
Broad, whose impressive batting at No8 gives him a second string to his bow, said: "Fred is a world-class performer and has done enough over his career to warrant a place in the side. I think any side in the world would put their hand up to have him."
Whatever the make-up of England's attack at Lord's, they face a South Africa batting unit already full of runs on this tour after making 515 for three against Somerset - even without captain and senior opener Smith, who is nursing a hamstring injury.
"Every Test is massive, but South Africa will be the highest-ranked team I've played against," said Broad. "It's going to be a very big challenge, if I'm selected, and it's something I'm looking forward to.
"They've got some world-class batsmen but we are in good shape as well and we're eager to get going."
