He hasn't even completed a full year as an England player, but Immanuel Feyi-Waboso has already made such a telling impact that his absence from the Six Nations represents a savage setback for Steve Borthwick.
The 22-year-old Exeter winger has quickly become a game-changing, match-winning asset for the national team since head coach Borthwick selected him for last season's competition.
Feyi-Waboso just looks at the way he was born. He looks like he belongs in international rugby and looks set to light it up for many years to come, scoring a host of tries in the process.
There have been so many glorious glimpses of dazzling repertoire. Feyi-Waboso landed five times in his first eight Test appearances, after pledging allegiance to England over his homeland of Wales.
In particular, he was able to score in three consecutive matches against the All Blacks; two in July and one in November, to show off their pace and footwork, their spatial awareness and their power in contact. He has also shown that he is a brave and tenacious defender.
There was an explosive first try against Scotland at Murrayfield last February and, in England's next match, Feyi-Waboso played a key role in an epic victory against Ireland at Twickenham, which remains the only decisive result of Borthwick's tenure until the date.

He has not even spent a year with England and his absence is a blow to Steve Borthwick.
The newcomer's late break set in motion Marcus Smith's drop goal which brought the house down and secured a surprise 23-22 victory against the eventual title winners.
Borthwick is not a natural selection player, but he quickly realized that this exciting rookie deserves to be a fixture in his team.
Unfortunately, the early stages of his Test career have been marred by injury problems. A concussion ruled him out of last year's Six Nations final against France and a similar problem interrupted his participation in the recent Autumn Nations Series.
So how will Borthwick respond? Their plans are quickly falling apart, certainly in the bottom three.
Starting full-back George Furbank will miss at least the first two games (against Ireland in Dublin and the home clash against France) with a broken arm, and now this. It's not ideal. At all.
In theory, the next cab out of the queue is Northampton flanker Ollie Sleightholme, but he was withdrawn from the Premiership clash with league leaders Bath on Sunday.
Phil Dowson, Saints director of rugby, said: “He felt his hamstring tighten. One of the things that ruined him early in his career was the soft tissues. We are always very aware of that and we manage it. properly, that's why we took him out of the game.
“I don't think it's that bad, but before they do scans and a couple of days to get a feel for it before it opens up again, I can't tell you how bad it is.”

Borthwick faces that with first-choice full-back George Furbank also currently absent.
The injury may dent the Lions' hopes for Feyi-Waboso, but head coach Andy Farrell could still conclude that the winger and his X-factor talent are too good to ignore despite his limited experience.
If there is any doubt over Sleightholme's availability, Sale's Tom Roebuck could be another candidate to start at full-back.
He scored his first Test try against Japan in November in a promising cameo and his aerial prowess increasingly plays in his favor amid a crackdown by officials against so-called “escort” runners.
Feyi-Waboso had to consider the best course of action himself and it is to Borthwick's credit that, armed with the trump card of the Professional Game Partnership agreement, which gives him the final say on medical matters, he did not try to force approval . the decision to go to rehab and continue playing.
Instead, medical student Feyi-Waboso evidently made a sensible decision with his long-term well-being in mind.
In the short term, this will deprive him of more England caps, but there will be plenty of them in the coming months and years. Beyond the Six Nations, it means he can be at full speed for the business end of Exeter's season and a summer tour.
He has already done enough to emerge as a contender for the Lions' tour of Australia. Ideally, head coach Andy Farrell would have wanted more evidence of the annual championship, or premier league and Champions Cup matches, of which the Chiefs will not be a part.
But Feyi-Waboso is a rare, X-factor talent, and Farrell may yet conclude he's too good to ignore.
