Shaun Edwards is certain Wales will not be undermined by complacency as they seek to continue their Six Nations dominance over Scotland at the Principality Stadium on Saturday.
Wales have won each of their last eight matches against Scotland in the competition - the latter's last victory in clashes between the two coming back in 2007.
In addition, a 15-9 reverse to England last weekend represented Scotland's eighth Six Nations defeat in succession - their worst streak since Italy were added to the tournament in 2000.
Nevertheless, Wales defence coach Edwards said: "This is a very, very determined squad and despite our good record against the Scots in recent years there is absolutely no danger of any complacency creeping in - none whatsoever.
"We have massive respect for Scotland who, like us, were one refereeing decision away from reaching the semi-finals of the Rugby World Cup earlier this season."
Wales, who will hand a 50th cap to Jonathan Davies, came from 13-0 down to draw 16-16 with champions Ireland in Dublin on the opening weekend of the tournament.
Edwards added: "Winning the championship is still within our own hands, although we know we will have to win our next four games and potentially beat Ireland on points difference to do that."
There was a significant boost for Wales coach Warren Gatland on Thursday when fly-half Dan Biggar was passed fit to start in an unchanged side, despite suffering an ankle injury against Ireland that was expected to rule him out for a number of weeks.
"It's been a pretty remarkable recovery really," Biggar told WRU TV.
"I've had my foot in an ice bucket for the last four or five days, whatever it's been, just getting a lot of treatment and resting up. Luckily it's just healed up nicely over the last couple of days and is nothing too serious."
Saracens centre Duncan Taylor replaces the injured Matt Scott in the only change to the visitors' line-up, while skipper Greig Laidlaw is set to earn his 48th Scotland cap, taking him past the tally achieved by his uncle, Roy.
Scotland have agreed to the Principality Stadium roof being closed for Saturday's match, a move welcomed by Wales.
Vern Cotter, Scotland's coach, said: "Yes, we'd like the roof shut. Why? In case it rains. We would like to be able to play the game, we'd like to be able to hang on to the ball."
