Ralf Rangnick says the Manchester United board must let the next permanent manager rip up the squad in the summer if they want to challenge Manchester City and Liverpool.
United are in the process of interviewing candidates for the job, including Ajax manager Erik ten Hag and Paris Saint-Germain coach Mauricio Pochettino. Rangnick says he has already advised the board that the new man needs significant backing in the transfer market while also recommending the club sign more "physical players."
