Jason Gillespie knows what Jofra Archer has to do to get in the England team.

And it is not exactly rocket science.

The Sussex fast bowler just needs to keep doing what he is doing.

Archer took back-to-back four-wicket hauls as his side bowled out Glamorgan in two sessions at Hove on Monday.

It is believed, but has not been confirmed, an ECB talent-spotter parked up at the ground in time to see Archer’s blast of 4-4 off 11 balls to start the mayhem.

You would have got long odds at that stage of him missing out on a five-for.

But, when he took the final wicket of the day by bowling Lukas Carey, he had figures of 8-46 from two astonishing sessions.

Reports suggest Archer could become available for England next year rather than in what seems the far-off 2022.

So whoever who was watching on Tuesday, be it at Hove or from afar, will have taken note.

Gillespie believes they would have been impressed – but not shocked.

The Sussex head coach said he had no knowledge of an England scout being present.

But he added: “I think they know what he can do.

“I think he is a fine young bowler, fine young man and he has just got to continue to put the performances on the board and learn each and every day and things will potentially take care of themselves in the future should he become available to play.”

Archer was as laid-back as ever after his eight-wicket day.

It was easy to forget it was his first Championship match at Hove for almost a year.

Asked by The Argus whether he was aware of a potential rule change which would clear him for England consideration, he told The Argus: “I’m aware but I don’t really keep track of it.

“It if happens it happens, if it doesn’t it doesn’t.”

Gillespie was delighted to see Archer asking more questions of the batsmen than he did at Gloucestershire in the previous fixture.

And he included the more experienced Chris Jordan in that observation. Speaking about Archer, Gillespie said: “I remember saying a few weeks back that, after coming back from the IPL and winter playing short-form cricket, it was just taking him a little while to find his feet and get back in the swing of it.

“He has just shown again what a quality performer he is.

“Give him a lot of credit.

“He has been working very hard at his game and homing in on his lines and lengths compared to one-day cricket, where you use more variations.

“He is locked in on that really good, fullish length with the odd bouncer and the odd yorker.

“He has shown what a fine bowler he is.

“I thought he bowed quite well at Gloucestershire but he went up a notch again.

“It’s just that continual improvement.”

Jordan took up the baton just as Glamorgan were finding a way to hang on against Archer in that first innings.

He finished the day with figures of 3-23 followed by 2-14.

Two of his five wickets were bowled, one was caught behind and another was held in the slips by Phil Salt.

A catch at mid-on by Archer, of course, was also in that tally.

Gillespie said: “We spoke to Chris about the length he has bowled.

“We just felt at Gloucester he was probably a tad short and probably a foot wide of the crease.

“The Gloucester boys let a lot of balls go through to the keeper, so not really challenging that off-stump or challenging the defence of the batters.

“Here, he got bowleds and nicks off the front foot, which suggests he is getting his length right.

“I am really pleased that a senior player is able to adapt and adjust his game.

“To be fair to him, he has played a lot of one-day cricket with the white cricket ball.

“He hasn’t played a lot of four-day cricket.

“It has been great that an experienced player has been able to adjust so quickly to four-day cricket.

“Between games he has adjusted his skills.”
