You're assuming that the consequences will be the same, which I doubt.
If it was one of those three trying to catch us, I'd be worried, but all three seems massively unlikely. Chelsea can only play 45 minutes of good football and United look so brittle. The first bad defeat and they'll collapse into old habits. Liverpool have an insanely tough run in also, you'd be hard pressed to pick harder fixtures for them in the last 4 weeks.
