I didn't actually know that no lower-half sides had won there this season without checking. I just recall some recent 5Live coverage about the stark difference between their home and away form this season.
They've lost once in the league at home this season, and that was to City. Believe their only other home loss of the season was to United in the cup. Couple that with just two draws in the league and it's clear getting anything there is gonna be difficult.
