Blackwell was appointed manager of Sheffield United after Bryan Robson stepped down in February, leaving United in the brink of possibly relegation.
Since then the team has been rejuvenated by a run which has brought maximum points in the last four fixtures against; Plymouth Argyle (1-0), Coventry City (2-1), Norwich City (2-0) and a single Billy Sharp effort against Barnsley last Saturday has given Blades fans fresh hopes of returning to the Premiership.
Blackwell said: "There's a lot of work to do and it's not in our hands to be fair. What we've said we've got to try and do is just keep winning games and let's just see what happens.
"What I do know is the players believe a lot more in themselves and can win at home and away. That's two away wins back-to-back now and two homes wins.
"We've got to go to Preston and try and get a result and if we can do that it will be very interesting to see what happens."
That result at Barnsley leaves Sheffield United within six points of the Play-Off pack and with just one game in hand gives the Blades a really good chance of finishing in a top six spot come 4pm on 4th May 2008.
