It is absolutely not us or Chelsea, and the above scenario is not likely - in fact it's incredibly unlikely. According to the odds we are currently 91% chance of qualifying, Chelsea are at 54% chance of not qualifying. The above is assuming:
Forest beat Leicester
Arsenal draw to Newcastle
Villa beat Spurs
Villa beat United
Chelsea beat United
Forest beat West Ham
Chelsea and Forest draw
We fail to beat Bournemouth
Arsenal beat Saints
Newcastle beat Everton
If all ten of those results come in exactly like that, I will donate £10 to a charity of your choice :)
