Boss doesn't want his side to waste the chance of reaching Wembley.
Michael Appleton believes that Rovers have to go into this afternoon's FA Cup quarter-final clash with Millwall with the same attitude that has seen them reach this stage of the competition.
Rovers have seen off Bristol City, Derby County and Arsenal to make the sixth round of the FA Cup, the side and have yet to concede in this season's competition. A feat only matched by fellow last-eight team Manchester City.
Appleton is insistent that his players don't underestimate a Millwall side who have defeated Preston North End, Aston Villa and Luton Town to make it to the quarter-finals.
"We need to ensure that when we go into the game against Millwall that we do it in the same frame of mind as we did against Derby and against Arsenal," said the Rovers boss.
"I'd like to think that the results of late will stop any complacency going into the game. It is a great opportunity to get to a semi-final, I think everyone realises that.
"I've not had a proper look to see who in my team has played at Wembley but it isn't a massive amount of players, so motivation shouldn't be a problem."
Tickets for Sunday's cup tie will be on sale at The Den from the North Stand ticket office from 12 noon.
Prices are £20 for Adults, £11 Seniors aged 60 and over, £10 for Juniors under 16.
Supporters who are unable to get to London to watch Rovers in action can see the game live in Blues Bar or online on Rovers Player.
