Liverpool’s charge towards the Champions League places has been curtailed by defeats to Manchester United and Arsenal but midfielder Henderson feels the Ewood Park result will help get things back on track.
“It was a really important game for us today,” he told BT Sport. “I think everybody has been disappointed over the last couple of weeks with performances and results.
“But I think we showed great character today. We knew when we came here they’d make it difficult for us but from start to finish we controlled the game, I thought we were brilliant.
“Towards the end when we’d gone 1-0 up they were chucking everything at us but we defended fantastically.
“Credit to the lads really and we’ll go to Wembley against Villa and I’m sure it will be a tough game because they’re a good side.
“But it gives everyone a lift.”
Brazilian playmaker Coutinho drilled home Liverpool’s winner after a swift interchange with Henderson and the latter hailed a “little bit of brilliance” from the man signed from Inter Milan two years ago.
He added: “Philippe’s got a great football brain and the easy bit was just giving him it and he finished it fantastically well.
“That little bit of brilliance from him wins us the game and gives everyone a big lift.
“Hopefully now we can kick on over our last seven games in the Premier League and in the semi-final.”
