BBC Radio Lancashire:
"DJ brings goals to the squad and he's got vast experience of this level.
"Lee is not as high-profile, but he's a player I think very highly of. He's very underrated and I think he'll be a success at Blackburn.
"I want to bring players who've got a point to prove and who are desperate to be successful. DJ and Lee are certainly players of that pedigree.
"I'd rather have a smaller group of players of true quality, rather than a massive group of players when it's all about quantity and not much quality."
Appleton added that he would be willing to allow strikers Nuno Gomes and David Goodwillie leave the club on loan, while he admitted that former Rovers and England man David Bentley is on a list of "five or six" wingers he is interested in signing.
Speaking after completing his move to Blackburn, the former Blackpool man said: "I've got nothing against Steve. He's a good guy. I'm a little bit disappointed with the way he said things because, in my eyes, a lot of it wasn't true.
"I just decided on Blackburn - that's all it was. I'm happy with my decision."
