I know that there have been upsets recently but the likelihood is that Blackburn will go down because even if they beat Wigan at home, they are unlikely to get another 4 points from Chelsea away and Spurs away.
That leaves QPR in my opinion at the other most likely team to go down. I think that Chelsea will win tomorrow at the Bridge - QPR are not great on their travels and although Chelsea are in a European Final, the banned players means there's no need to rotate the likes of Ramires, etc. Yes, they'll be fatigued, but good enough to beat QPR, I believe.
That means that as long at Man City win on the final day, we'll be ok.
Incidentally, I think QPR will only get a point at home to Stoke and we'll get a point against Norwich or Spurs, so we'll be ok anyway.
The problem is that without the elusive win, we're still in the mix and that's why McLeish should - and will - leave in the summer.
