It's uneasy times for Liverpool. Their Premier League title hopes hinge not on what they can do but on what Manchester City will do on the final day on Sunday. Before that, they will host Lionel Messi and Barcelona in the second leg of their UEFA Champions League semi-final fixture. And worryingly, there will be no Mohamed Salah -- the lone bright spot in their 0-3 defeat at Camp Nou. The Egyptian will not be the only major absentee. Mercurian Roberto Firmino is also out.
