JAMIE Roberts says there have been a few homes truths dished out in a forthright team meeting as Wales prepare to try and kickstart their Six Nations in Edinburgh.

Warren Gatland's men made a woeful start to the tournament when outplayed by England at the Millennium Stadium in a 21-16 defeat.

Their shortcomings have been addressed at the Vale of Glamorgan headquarters but powerhouse centre Roberts believes they can't afford to dwell on them as they attempt to repeat their efforts of 2013, when they lost to Ireland but rallied to win the title.

"There have been a few harsh and honest words said. We have to move forward as a team," said Roberts.

"Two years ago we showed we can bounce back, and we have to look to do the same in this tournament.

"The Six Nations is too short a tournament to dwell on what happens one week, moving to the next. We will learn from our mistakes - and there were quite a few - and we will move forward.

"We are playing a very good Scotland team on Sunday that is much improved. It is going to be a massive game."

While Wales spluttered against England on Friday night, the Scots produced a spirited display in defeat in Paris.

They have made strides under Vern Cotter and will be quietly fancying their chances of ending an eight-year wait for a win against Wales, a record that goes back to before Gatland took the reins.

Roberts said: "Having seen us play Friday night, and the way we did play, which was thoroughly disappointing, they will be rubbing their hands together. There is no doubt about that.

"I think we are a team that plays its best rugby when our backs are against the wall, and you will certainly see a very motivated Wales team at Murrayfield."

Wales have been criticised for lacking spark against the English and Roberts hopes that the pack can thrive to enable them to be more creative.

"The set piece was disappointing," he said. "We didn't manage to play on the front foot too much. Rugby is a game that needs to be played on the front foot in order to play an expansive game."
