I'd make a change or two as well, given who we have coming up afterwards. Like others, the only ones I can think of changing are(or because of injury the only ones we can) Skrtel and Johnson. I would like to see Kelly get some game time, but no harm in Agger or Toure coming back in.
The flip side is that this game shouldn't be too tense for the defense if played right. I'd maybe change Johnson but then do you effect his confidence ahead of such crucial games? Johnson has never been one to fair too well after a game or two on the sidelines, he's under par defensively as it is.
Continuity should be the key, but I'd be looking to rest Suarez, Allen (because he's not long returned) and coutinho as soon as possible in the game, if we can get it won early.
This is an ideal time for Kelly, Alberto and Aspas to get some game time. It might even be ideal to give one of the defenders a run out in midfield just to shore things up and give someone a breather.
