Don't forget to secure the play offs, we must equal Boro's result or do better. So if they lose, no matter what our result we will be guaranteed play offs, if they draw, we have to draw or win and obviously if they win, we need to win.
But i also worked out that if they draw we can also lose, if they win 1-0 and we lost 1-0 tomorrow then their goal difference would be +2 and ours would be +11. So they could win on the last day of the season and we could still lose, then we would be in the play offs on goal difference, and come on, are Boro really gonna beat Watford away 10-0?
