Jurgen Klopp lamented the lengthy injury problems for Diogo Jota after his double helped Liverpool to a 6-1 over Leeds United on Monday.
Jota registered his first goals for 12 months in the Elland Road hammering as the Reds closed the gap on the top four to nine points with eight games left to play.
Portugal international Jota was sidelined between mid-July and early September at the beginning of the season with a hamstring complaint before a serious calf injury left him out for four months prior to his February return.
