It would be foolish to think that every other game will go to plan, so worrying about goal difference etc is slightly premature. A draw with both dropping points wouldn't be the worst thing in the world - to be honest, as long as Brighton keep winning, no result is *that* bad. Its a great time...
The alternative viewpoint of course is that if you can get within 2 points of Boro by the final day, that game effectively becomes a final.
Cliche but theres still a lot of football to be played - win Friday and see if either Boro or Burnley drop points Saturday - theyre both away from home so...
