Having been promoted as Sky Bet Championship runners-up, Chris Wilder's men have been the surprise package of the 2019-20 season and sit seventh in the Premier League standings.
Not only are they tantalizingly close to European football with 10 matches to go but they have an FA Cup quarter-final against Arsenal to look forward to.
Osborn knows it will be hard to pick up where they left off following the three-month coronavirus suspension, but the Blades' determination to capitalise on their surprise position is clear.
"It's going to be tough to carry on from that, the whole world has changed since we last played a game," the midfielder said.
"We've just got to attack it like a mini season, with the last few games and the FA Cup to play. We've got to try to condense it and hopefully do something special".
