struggling on the site here, want 4 adult tickets but the only sections with 4 tickets you need to have a junior with you or something! annoying.
ADULT/JUNIOR SEATING:ANFIELD ROAD - BLOCKS 124 & 125, ANFIELD ROAD UPPER, BLOCKS 224 & 225 AND KENNY DALGLISH STAND, BLOCKS KH & KJ.
That's from the site, so I guess there are not 4 together in the other blocks at the moment. Keep refreshing and someone might drop them out of the basket
EDIT: actually just try clicking on the individual block and selecting 4 together. Just done it in 127 lower anny road and it lets you.
If you try 'any block' it defaults to the adult/junior blocks, maybe as they have more availability
