MK Dons boss Karl Robinson felt his side's 2-1 Capital One Cup giant-killing of Blackburn was a "comfortable" victory.
Luke Chadwick netted a second-half brace before David Goodwillie nodded in an 83rd-minute consolation goal for Rovers as the Dons claimed a richly deserved place in the third round.
And Robinson said: "It was comfortable, I'm very pleased because it was a very professional performance.
"We looked very accomplished and we move on from here with tremendous mental strength and belief in ourselves.
"The first five minutes they started OK but once our two midfield players got to grips with it we were the better side.
"It was lovely writing the team sheet and putting Stephen Gleeson and Darren Potter together - it made me a lot happier.
"We looked good but I just don't want to go over the top because it's a cup game and we need to move on from here very quickly.
"Luke Chadwick likes scoring goals in August but he needs to liven himself up in September, November and December as well.
"He was just very good, the fact that he was in the right place at the right time shows that he's a good footballer.
"We just now need to dust ourselves off and make sure that we're all getting ourselves fighting and fit for Carlisle on Saturday."
Milton Keynes controlled most of the match and Chadwick calmly slotted home Jon Otsemobor's cutback to put them ahead after 51 minutes.
Chadwick doubled the Dons' lead 15 minutes later when he tapped in the rebound after Daniel Powell's shot had been spilled by Jake Kean, before Goodwillie headed in Fabio Nunes' cross late on for Rovers.
Blackburn boss Steve Kean once again endured chants of "Kean out" from the travelling fans towards the end and he admitted his team were below par.
He said: "I never thought we played well, I felt that we were a little bit predictable in the end.
"The ball wasn't sticking from the front and it was difficult for young Edinho because he's not got the physical presence yet, but he was working his socks off.
"I think we could have helped him a bit more by, when the ball was going up to him, giving him an angle that he could get onto that wasn't a straight one.
"I felt that we had to get the ball in behind the full-backs much more because when we did, like for the goal, then we've got players that can finish high-quality balls.
"Obviously we made a few changes because the older players in the squad, by the time we get to Saturday, if they had played it would have been five games in 14 days.
"So it was an opportunity for some players who have not played as many minutes as others to get the chance and it was up to them to take it."
