Wales have leapfrogged England into third in the latest set of global rankings, with Ireland remaining in second position behind world champions New Zealand.
Warren Gatland's men are the only team still capable of winning the Grand Slam after a stunning 21-13 victory in Cardiff on Saturday propelled them to the summit of the Guinness Six Nations table.
Despite the opening round defeat to England, wins over Scotland and Italy ensure Joe Schmidt’s side remain the closest challengers to the All Blacks.
England, who were labelled chokers by Gatland in the wake of their second-half implosion at the Principality Stadium, drop to fourth in the rankings compiled by World Rugby.
Wales have fixtures with Scotland and Ireland to come, but with Italy and Scotland due at Twickenham it is England who remain bookmakers' favourites to win the 2019 Six Nations.
France are also on the move after their 27-10 victory over Scotland in Paris lifted them two places up the standings above Argentina and Fiji. However, they remain one spot below their victims in Paris.
France meanwhile have called on lock Paul Gabrillagues as the only change to their squad for the Six Nations encounter with champions Ireland in Dublin on Sunday week.
Gabrillagues replaces the injured Fabien Sanconnie, who did not feature in Saturday's bonus-point 27-10 victory over Scotland.
Sanconnie was himself a replacement in the squad for Bernard le Roux.
