The Netherlands international has racked up four goals and five assists from 45 appearances in all tournaments this season - starting 29 La Liga games for the second-placed Blaugrana.
De Jong remains contracted to Barcelona for another four years, but his future has been called into question in recent weeks amid suggestions that Man United are keen on signing him.
Furthermore, the Catalan giants are set to welcome Franck Kessie to the club as a free agent from AC Milan, and Xavi is reportedly keen to further bolster his midfield options.
As a result, Cuatro Deportes now indicates that the Barcelona manager has given his blessing for De Jong to join Man United, seeing his Blaugrana stint end after a three-year spell.
Given the club's dire financial situation, Man United were supposedly set to secure the 24-year-old's signature for a cut-price figure of £51m in the upcoming transfer window.
However, the report adds that Barcelona will instead pocket €75m (£64m) for the sale of De Jong, who has 'not achieved what was expected of him' following his arrival.
The former Ajax man, who has amassed a total of 13 goals and 17 assists in 138 games for Barcelona, is said to be open to his imminent departure as he prepares to reunite with Erik ten Hag.
De Jong rose to prominence under Ten Hag at Ajax and played an integral role in his side's run to the 2018-19 Champions League semi-finals before joining Barcelona for £77.4m in the summer of 2019.
Barcelona have also waved goodbye to Philippe Coutinho - whose departure to Aston Villa on a permanent basis was announced on Thursday - and have supposedly identified Bernardo Silva as an ideal replacement for De Jong.
De Jong's signing could reportedly be announced by the Red Devils before the end of the season, and his next and final game for Barcelona could therefore be next weekend's La Liga clash with Villarreal, as he will serve a suspension in Sunday's meeting with Getafe.
