"We know we are a lot better team than our performance against England last Friday would suggest," said Hayward. "We lost the physical battle in that game and missed a huge number of tackles.
"Individually and collectively, that display is not what we've come to expect over the last couple of years. But we have a chance to put that right on Friday in our last competitive game before the Junior World Championship."
Wales Sevens' Ashley Evans moves to full back from wing for Friday's clash, with Joshua Adams coming back onto the left wing and Luc Jones, son of Dragons director of rugby Lyn, getting his first start at scrum half. In the forwards, RGC flanker Olly Cracknell will make his Wales Under-20 debut, hooker Scott Otten makes his first start of the campaign and Will Boyde starts on the openside flank."
Hayward added, "We won't be underestimating Scotland in any way but we need to concentrate on improving areas of our own game this week."
