Just down the street from Carraghers is Stout, which is also on John st, and I've watched a few games there (10am kick offs though - 7.30am is an v early start so might want to check if it's open). It doesnt get crazy busy so getting a seat isn't too hard if you get there just before kick off. Carragher's is always tough to get into but the atmosphere is great, so maybe worth trying there first.
11st bar is an amazing spot but you need to get there early.
