The trio have all been absent for different reasons over recent weeks, but returned in the midweek loss to West Ham United in the FA Cup.
Coutinho immediately showed his quality with a clever free kick to level the scores after Michail Antonio’s opener.
Sturridge and Origi were brought on as substitutes later on, with the former showing the sort of quality that has been lacking from the Reds attack this season.
And Milner says he is hopeful the return of all three can help them to start scoring the goals they need as the season comes to a close.
“There’s a lot of pace there, a lot of ability and goals,” he told Liverpoolfc.com.
“We are creating chances at the moment but they aren’t quite going in so to have those three back should help that.”
“Missing those three is obviously big and it gives us a lot of options and there’s a lot of quality there.”
In particular, Liverpool will be hoping that Daniel Sturridge can remain fit between now and the end of the season.
His quality has been sorely missing from the side this season, with Christian Benteke struggling to live up to the big price tag that accompanied his move from Aston Villa in the summer.
If he could come back and stay fit until the summer, it would surely be a huge boost to the Reds’ hopes of qualifying for Europe next season
