As 'Boro push for an automatic promotion spot, there is a very real possibility that both Sunderland and Newcastle United suffer relegation to the Championship.
Both teams sit in the Premier League relegation zone in 18th and 19th place, with 17th positioned Norwich City pulling away at the weekend with a 3-2 win over Newcastle.
Middlesbrough meanwhile had a 3-2 win of their own against QPR to propel them into second place in the Championship, with a game in hand on leaders Burnley,
Redknapp told The Mail: "Who would have thought that next season the only North East team in the top flight could be Middlesbrough?
"That was a big win at QPR on Friday and whoever calmed the situation with manager Aitor Karanka deserves credit. They steadied the ship and now Boro look like one of the favourites to go up."
Redknapp went on to point out that next season could be the first without either Newcastle or Sunderland in the top flight since 1992/93.
Karanka peculiarly walked out in the middle of a team meeting last month, and was not present in the dugout as they lost to Charlton Athletic.
The former Real Madrid assistant has since put differences aside, and Middlesbrough have won their last two games, and with three consecutive home games to come next against teams outside the top nine positions, there is reason to be optimistic again.
