Willis enjoyed a fine 2018/19 season, first shining in the Premiership Rugby Cup and Shield before earning his first Premiership start in November 2018 v Northampton Saints.
He went on to play six times for the first-team during the 2018/19 season and scored his maiden Wasps try in November 2018 v Northampton in the Premiership Rugby Cup.
Willis represented England Under 20s in the same season, scoring four tries in five appearances at the 2019 Six Nations and also captaining them in their final three games of the tournament.
Willis also impressed in the 2019 World Rugby Under 20 Championship in Argentina – scoring three tries, including an 80th-minute match-winner against Ireland.
