Roberts: We let people down
Jamie Roberts has admitted that Wales let down their supporters with a dire display against Argentina in the opening autumn Test last weekend.
The reigning Six Nations champions will be back in action on Friday night when hard-hitting Samoa arrive at the Millennium Stadium.
Centre Roberts, who went off concussed after being knocked out following a clash of heads in the first-half of the 26-12 loss to Argentina, hopes to be involved in that fixture.
And if he successfully comes through the necessary medical-related protocols, then he is likely to feature in Wales' starting line-up when it is announced later today.
"We let the Welsh public down on Saturday, and the players are well aware of that," Roberts said.
"We were below-par as a team and we must redeem ourselves at the next opportunity. We will give it our all.
"They (Argentina) beat us at home, which is hard to take, but rugby gives you the chance to make amends very quickly.
"To have a six-day turnaround and to play against a team like Samoa is a great opportunity to put things right and redeem yourselves."
Interim head coach Rob Howley's line-up will feature a minimum of two changes, given that lock Alun-Wyn Jones (shoulder) and flanker Josh Turnbull (knee ligaments) have both been ruled out of remaining autumn appointments with Samoa, New Zealand and Australia.
Luke Charteris and Ryan Jones are the likely replacements, while there could also be opportunities for fly-half Dan Biggar and hooker Richard Hibbard as Wales target a first victory since they beat the Barbarians more than five months ago.
"I have huge respect for teams like Samoa. They are big, physical guys and they are really good rugby players," Roberts added.
"We have played against them a few times in the last four or five years, and in 2009 they would have won if they had not dropped the ball over the line in the last minute.
"And I remember the match in the World Cup last year, which was probably one of the toughest matches of my career.
"You have to match these sides physically to have any chance of competing.
"We have to be less tactically na? than we were on Saturday, when we did not play in the right areas.
"We played too much rugby in our own half and on halfway, and we cannot afford to do that against Samoa. We also have to get our defensive structure right.
"We have to be on the money from the start of the game, which we were not last Saturday."
