Bury face relegation rivals Portsmouth on Saturday ahead of back-to-back home games against Scunthorpe United and Colchester United. Blackwell has claimed that these matches could prove crucial in the club's survival bid.

"We had to get into a position where we could at least have a chance to get out of it. That's what we've done and I don't want us to mess that up.
"This month was the chance for us to get out and all the way through it's been about trying to get to a point of getting out."
