The 26-year-old has started the last two matches for the Blades and netted the winner in the 1-0 win over promotion rivals Reading on Good Friday.
The former Barnsley midfielder completed a permanent switch to United in January following a successful loan spell but will miss Monday's clash with Burnley due to a two-match suspension.
He told the club's official website: "Everybody wants to play every week but when you come to a new club that has over 20 players that are capable of starting you have to appreciate it will be tougher.
"I have got my head down and worked hard. The toys haven't been chucked out of the pram and in the last couple of games I think I have done ok.
"I do whatever the gaffer asks me to the best of my abilities."
