As Red said, if Milner is fit, he plays & Klopp will most likely go with a 4-3-3 formation with Hendo, Gini & Milner in the midfield.
Or will he surprise & go with a 4-2-3-1 formation & a Fab-Keita double pivot midfield shape? Fab prefers this, but I’m guessing that Klopp won’t start with this formation. Would be exciting to see it, though.
Bobby is hitting a rich vein of form & will trouble Stones. City have a number of headaches to deal with.
