Six Leicester Tigers players were on show for their respective nations during the opening weekend of the 2021 autumn series.
Ben Youngs helped lead England Rugby to a dominant victory over Tonga at Twickenham in their autumn series opener on Saturday afternoon.
The Leicester Tigers scrum-half scored a double in England's 69-3 win, which doubled as his 110th Test appearance for his country.
Leicester skipper Ellis Genge was at his barnstorming best in front of the busiest Twickenham crowd for more than 18 months, with seven carries, including one line-break which led to an England try in the first half.
Freddie Steward, in just his third Test appearance, proved a calming influence at the back for the home side.
The Tigers youngster was strong under the high-ball, helping the home team to evade the attacking ability of the Pacific Isles nation on several occasions, and showed his ability in attack as wide option for Eddie Jones.
Elsewhere on Saturday afternoon members of Steve Borthwick's squad were on show in Cardiff and Paris.
Jasper Wiese was a second-half replacement for the Springboks in South Africa's defeat of Wales 23-18 and Tigers duo Julián Montoya and Matías Moroni were starters in Argentina's narrow defeat to France.
Wiese was brought on for Springboks skipper Siya Kolisi in the 71st minute in the Welsh capital, proving difficult for the home side's defence with his strong carries and playing a key part in the driving maul from a line-out for the visitors to score the pivotal, match-winning try.
In the French capital, Los Pumas skipper Montoya was at his menacing best in attack and defence for Argentina.
The front-rower made 12 tackles, the third most of any player from either side in the match, and proved an inspiring figure for his team in defence with a physical showing.
Meanwhile, out wide, Moroni proved difficult for the French defensive line with his elusive footwork and strong carrying in attack, while showing his ability to break down momentum in defence.
England now turn their focus to Australia, on Saturday (November 13) at Twickenham while South Africa travel to Scotland and Argentina to Italy in the second weekend of autumn series fixtures.
