Alan Mullally writes for the Daily Echo.

Four years ago I said that Steve Harmison had the talent to become the best bowler that England has ever had and he is well on the way.

Harmy has always had the ability to bowl with more bounce and more pace than Glenn McGrath and now, at the age of 25, he is putting it all together and showing consistency.

It makes a huge difference to be able to run in without sore ankles and shins, or 'growing pains' as my old Leicestershire coach Jack Birkensaw would say.

And Harmy is now showing that he has passed the stage that Chris Tremlett is still going through.

In a few years time England could have an opening attack to rival the West Indies pair of Curtly Ambrose and Courtney Walsh in Harmison and Tremlett.

That is not unrealistic at all.

At 6ft 7in Tremlett is three inches taller than Harmison so the growing pains are inevitably going to be there.

But if he keeps working hard, there's no reason to say why he won't be at the other end to Harmison.

It's certainly a mouth-watering prospect to have two young men with such height sharing the new ball for England.

We have a quality bowling coach here at Hampshire in Bruce Reid and if Troy Cooley, the England bowling coach, is half as good, Tremlett is in safe hands.

At 80 mph, Tremlett bowls at a similar pace to McGrath and at 22 he has plenty of time to gain a yard or two of pace.
