Yeah, we'd have to win every game to really stand a chance of catching Chelsea and if we do that we'd finish at least 5+ points (likely 8+ given they go to Anfield) clear of Spurs. So yeah, doesn't change things one bit.
As far as pressure goes I don't think even being 5 points clear will alleviate it, this is one of those seasons where we just need to get it done to earn that pedigree.
