Burnley currently hold a four-point advantage over Middlesbrough at the top of the standings, while Hull occupy fourth spot but possess one game in hand on Boro and two on the Clarets.
Brighton & Hove Albion sit in third position, but Dickov, who has previously managed Doncaster Rovers in the second tier, is backing the teams around the South-Coast outfit to prove too strong over the final weeks of the campaign.
Dickov said: "I think regardless of who finishes in the top two, and with Hull having a game in hand, I fully expect all three teams to go up.
"I think the run that Burnley are on at the minute, and with the experience that they hae got, they know what it is like and they have Andre Gray, who is on fire at the minute.
"Middlesbrough have had a bit of a stutter recently, but whoever finishes first and second, I expect them to go up, and obviously one through the playoffs as well. Squad-wise, experience-wise and quality-wise, they are ahead of everyone else."
As far as form goes, Burnley are the standout team in the division. Sean Dyche's men have not lost since Boxing Day, with 10 victories and three draws being recorded since that away defeat to Hull.
Despite holding on to second place, Middlesbrough have won just three out of their last 10 matches, and host Hull next Friday.
Hull have been preoccupied with fixtures in the FA Cup, but after their 4-0 defeat to Arsenal on Tuesday night, they can now focus on matches at the KC Stadium with MK Dons and Nottingham Forest.
