I'd take taking points off either as it's not as if they're dead rubber games for us. We need the points as much as they do, just for different reasons.
I'd probably least want Liverpool to win the title, but I'm not thinking about that when we play City in early March. Plenty of time for them both to pick up and lose other meaningful points between then and the end of the season.
So if we can take points off either of them, I'd celebrate either scenario. Though I'd be amazed if we did get anything out of Sunday's game away at City (even with a full strength team, let alone with all our injuries). We've a bit more of a chance against Liverpool at home, at least.
