Jofra Archer's maturity and willingness to learn is already shining through in his thrilling start to Test cricket, says his county coach Jason Gillespie, report BBC.
Archer took five wickets on his debut against Australia and followed that with 6-45 in the first innings of the third Ashes Test at Headingley.
Sussex coach Gillespie said Archer, heeded advice on his bowling lengths.
"Jofra listens and in the space of one Test he adjusted and was rewarded," Gillespie told BBC South Today.
He starred for England as they lifted the World Cup for the first time, finishing as their leading wicket-taker and earning a call-up to the Test squad.
"In Test cricket, you have to play the long game," said Gillespie, who added that Archer's Sussex team-mate Chris Jordan has also provided useful advice to help his colleague adapt to international cricket.
"Sometimes I think Jofra's adjustments from playing T20 and 50-over cricket to the long form - and I have certainly seen it going from T20 to 50-over cricket - he looks to try a lot of different things when you don't need to.
"Jofra coming in has added a new dimension to England's attack. We have been saying at Sussex all along that he is ready to go. He has shown that - although he has only played two Tests.
"He is a pretty laid-back character and is doing a wonderful job so far in the infancy of his international career.
"He is buzzing. He is like a kid in a candy store playing for his country. He is absolutely loving it."
