If we win 2 out of 3 then second place is pretty well nailed on regardless of what West Ham do because of our goal difference. We win our games and we don't need to worry about West Ham. All we can do is go for maximum points and hope Reading slip up. They have a tough trip to St Andrews on the final day, while we have what should be a home banker against Coventry, so things could get interesting.
If WH win by three or four today, then I wouldn't be so confident about our GD advantage. Likewise, with regards to Brum vs reading on the final day, don't be surprised if Brum players have one eye on the play-offs already and/or Hughton rests a few players to ensure their availability.
Worst case scenario - Brighton get thumped today, then pick up form for final games, and get into play-offs as well.
And as for who they play and beat in the play-off final, I will not even start to think about that one.... revenge match against West Ham, let's say.
