Interim manager believes are only ‘two or three’ transfer windows away from competing with Liverpool and Manchester City.
The Red Devils are currently five years without a trophy and will finish on their lowest-ever points haul in the Premier League this season as they sit sixth ahead of their final game against .
New manager Erik ten Hag will take up his new role at Old Trafford in the next few weeks but will work with a squad heavily criticised by the club’s fans for a lack of quality and desire.
However, Rangnick, who took over from in November, says if United improve their recruitment they could be competing for the title sooner than expected.
Speaking ahead of their match against Crystal Palace, he told reporters: ‘If we bring in the right players, mentality players, I am positive we will be able to bring this club back to the top.
‘Maybe not possible in one window, but next two or three.’
Since Sir Alex Ferguson retired in 2013, United have spent over £1billion on new players, although most have failed to live up to the billing.
Last summer, the Manchester giants signed Jadon Sancho and Raphael Varane for over £100million, with both enduring disappointing seasons.
Meanwhile, the likes of Aaron Wan-Bissaka and Harry Maguire, bought for significant fees in 2019, have also performed poorly.
In contrast, Liverpool have been commended for their work in the transfer market, with Thiago Alcantara, Luis Diaz and Diogo Jota all turning out to be hits in the Premier League over the last two years.
Speaking after United’s 4-0 defeat to the Reds in April, Rangnick suggested the Red Devils could need as many as 12 new players.
Ten Hag will look to elevate United towards the title by bringing in fresh talent with Tottenham’s Harry Kane and West Ham’s Declan Rice linked with transfers.
But with no Champions League to offer and United struggling, a move to Old Trafford is not as tempting as it once was.
