United had been linked with a move for the former Liverpool star who could depart the Nou Camp this summer.
Liverpool are believed to be keeping an eye on Coutinho’s future while Chelsea may also be interested despite their transfer ban.
Coutinho shone during his time with Liverpool, coming close to winning the Premier League with the Reds in 2014.
But Spanish outlet Sport claim Coutinho won’t be moving to United should he leave Barcelona.
It’s reported that the Brazilian ruled out the Red Devils after being jeered during the first leg of Barcelona’s Champions League clash with Manchester United last week.
Coutinho doesn’t want to betray his former supporters and knows a move to United would do exactly that.
Speculation surrounding Coutinho’s future has continued to grow despite the 26-year-old insisting he is happy at Barcelona.
