Wales' hopes of retaining the Six Nations title were boosted by their 28-18 victory over Scotland at Murrayfield.
Interim Head Coach Rob Howley said the Edinburgh ground was not the easiest for any team to play and said he was "pleased" with his team's hard-fought victory.
Howley praised the performances of the Wales pack as well as the boot of Leigh Halfpenny who retained his composure after missing his first three kicks in Saturday's game.
Of Sam Warburton, Howley said he was "delighted" the centre was able to prove wrong those who questioned his abilities.
Ryan Jones' shoulder injury is being assessed and Howley is hopeful that Jones would be available for Saturday's decider clash against England. Howley told the post-match press conference in Scotland that Gethin Jenkins' calf injury was also improving and it is hoped he too will be fit for Wales' final game in this year's tournament.
All eyes are now on this Saturday's clash with Grand Slam favourites England at the Millennium Stadium. Howley described it as a "mammoth game" and one of the biggest games that the players and coaches will have been involved in, but having the "best supporters in world rugby" would help.
