England World Cup winner Will Greenwood believes Louis Rees-Zammit can become a rugby 'superstar' in the next few weeks - if Wayne Pivac picks him.
Greenwood has namechecked the Wales teen wing flier as one of six players to watch in the Autumn Nations Cup and feels he can even force his way into Warren Gatland's Lions Test XV.
But first Pivac needs to give Rees-Zammit a chance, having overlooked him again for Wales' tournament opener against Ireland in Dublin.
In a column for the Telegraph headlined 'The six players who could be superstars this autumn', Greenwood names the exciting aces he expects to wow the world.
The other five he names are each picks for their country - Anthony Watson (England), when fit, Ireland newcomer Hugo Keenan, Scotland wing Darcy Graham, French try ace Teddy Thomas and new Italy fly-half Paolo Garbisi.
Greenwood chooses Rees-Zammit as the Wales player to watch, although the youngster has been left out of matchday 23 for Dublin with Wales looking to halt a run of five defeats on the trot.
Rees-Zammit has lit up the English Premiership with his tries for Gloucester and shone during a cameo Wales debut appearance as a substitute versus France.
Pivac has gone with experience on the wing against Ireland, but Greenwood has no doubts Rees-Zammit will seize the moment if given an opportunity to start.
"What a year he has in store. Let’s assume the Lions tour is still on - the opportunity to grab a wing spot looks wide open," says Greenwood.
"The reality is that as the pace of the fliers get ever faster - particularly Cheslin Kolbe and Makazole Mapimpi - then the pace of Rees-Zammit at least gets him to Warren Gatland's thinking.
"We get to see if he can transfer athletic track pace to the international rugby field. There are lots of quick lads who do not play rugby. The ball transfer, ball flight and body movement are not always delivered by a sprinter's thoughts, that wants to simply use mechanics and technique to race clear.
"Adapting speed, to use the fast-slow tempo of rugby and to know when to hit accelerate and when to stay in third gear, will be his challenge.
"He has plenty of gas under the bonnet to use wisely if the game suits his eye."
