Liverpool received a huge boost when striker Mohamed Salah returned to training on Wednesday after spending more than two weeks out with a hamstring injury.
His return comes a day before Liverpool's Europa League clash with Sparta Prague, and four days before the Premier League leaders host defending champions Manchester City on Sunday.

Salah, who has scored 19 goals for Liverpool this season in all competitions, was previously injured while representing Egypt at the African Cup of Nations. He has not played since February 17, when he came off the bench and scored in a 4-1 win at Brentford.
Salah's status and potential return will become clearer later on Wednesday when manager Jurgen Klopp speaks to reporters ahead of the round of 16 match.
Liverpool, City and Arsenal are in a three-way race for the Premier League title this season, with the three teams separated by just two points after 27 games.
