The 31-year-old striker, who has joined Rovers on a three-month loan spell, knows that the task ahead will be a tough one, but he believes that the quality in the squad is there for all to see and that the points gap between Rovers and 6th place can be quickly closed.
"We're only seven points off the play-offs, but with the players that we've got, the gaffer, the squad, the club, everything about Blackburn is a Premier League club in my eyes," said Campbell.
"Seven points might seem like a lot but not in my eyes, like the gaffer said, we've got 54 points to play for so seven points in 54 doesn't sound like a lot.
"We've won the last two, kept two clean sheets so it is definitely do-able.
"For me the only way is forward and I believe we definitely can go on a winning run and get the points needed to get in the play-offs.
"Reading did it last year and in my eyes we've got a better squad than Reading had last year, it is doable, I'm sure we'll be fine, I'm confident we'll make the play-offs."
This Saturday could see DJ make his Rovers debut, against an Ipswich Town side where he enjoyed a fruitful loan spell earlier in the season.
And as he comes up against his former club, the striker has nothing but praise for Town.
"They're a brilliant club with a great gaffer and staff," added Campbell.
"I've nothing but positive things to say about the club and the people there, but now it is all about Blackburn for me."
See DJ's debut against Ipswich Town on Saturday. Tickets are on sale until the 3pm kick-off priced from £15 for Adults, £10 Seniors and from just £5 for Juniors.
