All three came off the bench in the 3-3 draw with Brighton, with Diaz assisting Roberto Firmino’s equaliser, and will hope for more minutes in what should be an intense atmosphere at Anfield.
Firmino, despite his two goals on Saturday, could make way along with Fabio Carvalho.
Trent Alexander-Arnold’s form has been under the spotlight of late and he did himself no favours against the Seagulls, but there is little danger of him losing his place.
Liverpool are still juggling a hefty injury list. Andrew Robertson and Ibrahima Konate are both nursing knee injuries and are nearing a return but the visit of Rangers will likely come too soon. The trip to Arsenal is a safer bet.
Naby Keita and Alex Oxlade-Chamberlain (both thigh injuries) are looking at the following week, while Curtis Jones and Calvin Ramsey, calf and back injuries respectively, are facing a longer spell of the sidelines.
Liverpool predicted XI: Alisson; Alexander-Arnold, Matip, Van Dijk, Tsimikas; Elliott, Henderson, Thiago; Salah, Jota, Diaz
Doubts: Andy Robertson and Ibrahima Konate
Injured: Naby Keita, Alex Oxlade-Chamberlain, Curtis Jones and Calvin Ramsey
