Scotland have lost their last two games, against Italy and France, but Burnell insists "we are taking no notice whatsoever of those results.
"Scotland are sure to be wounded by their recent results, and perhaps we could have taken the opportunity to look at other players, but we have respect for all our opponents and so we will field an unchanged team against the Scots.
"It was a fantastic victory over England because they are a very impressive side and the result was massive credit to the Wales squad as a group of players.
"We have created a close-knit enviroNment in the squad and last Friday was all about their never-say-die attitude and committment to playing for each other."
