The key in that statement is "we won"
A win for us will be enough - regardless of the rest
It might not be, Birmingham could win today against Huddersfield and then Norwich might not have anything to play for against them on the final day. Wednesday today are playing an out of form West Brom and then a Sunderland side with nothing to play for. They could both get six points from their final two games leaving them on: Birmingham 52, Wednesday 53.
That would mean after a win today we might still need another point, or for those above us to lose their games. Blackburn are playing an out of form Coventry today, and then a Leicester side who are already promoted. Stoke could be in trouble if they think they're safe already. They might be after today if results go their way, but Southampton will want to win today after their humiliation last week against Leicester, but they could get something against Bristol City on the final day.
A win today might be enough for us, but that would need other results to go our way for that to be the case.
