One of the many intriguing duels in store when Wales and England clash at the Principality Stadium on Saturday is a high-octane collision on the wing.
Gloucester team-mates Louis Rees-Zammit and Jonny May are capable of shredding defences with their pace and footwork and here, the PA news agency analyses both players.
Louis Rees-Zammit – Gloucester
Position: Wing
Age: 20
Caps: 6
Debut: v France, 2020
Height: 6'2"
Weight: 13st 9lbs
Points: 20 (Tries 4)
From the moment he made his Gloucester debut as an 18-year-old, Rees-Zammit has looked destined for the top. A lethal finisher with lightning-fast pace – even the jet-heeled May says that "on a good day I can just about keep up" – the Wales wing has taken to Test rugby with aplomb. Two tries against Scotland at Murrayfield, the second a clinical solo effort that swept Wales into the lead in a finely-poised match, signpost a long international career that could take a step forwards with Lions selection this summer. Still only 20, one of the challenges facing Rees-Zammit is to stay grounded.
Jonny May – Gloucester
Position: Wing
Age: 30
Caps: 63
Debut: v Argentina, 2013
Height: 6'2"
Weight: 14st 2lbs
Points: 160 (Tries 32)
By his own admission he may be a fraction slower, but May's all-round game has evolved to a whole new level. Still capable of scoring spectacular tries – witness his finishes against Ireland last autumn and against Italy in round two – but he now takes as much satisfaction in the less glamorous duties of the modern wing such as kick-chase and aerial ability. His dedication to his craft is unrivalled in the England camp and he has developed into a more rounded player. For all that, it is the extraordinary athleticism, ability to stop-start and eye for an opening that set him apart as a box-office attraction.
