That’s after the Reds made it into the Champions League final by beating Roma 7-6 on aggregate earlier this week.
Coutinho left Liverpool in January but was unable to play for Barca in Europa after featuring for Jurgen Klopp’s side in the first half of the season.
And the Catalan club saw their run ended at the quarter-final stage by Roma.
Spanish outlet Diario Gol, known for their bold claims, report Coutinho now wishes he had STAYED at Anfield.
And Barcelona are said to be angry with the Brazilian for making his feelings clear as they believe the image of the club has been damaged.
