The Blades are right on the edge of the promotion race, fighting for an unlikely top six spot, with a crucial clash with fellow play-off hopefuls Millwall this weekend.

Chris Wilder and Neil Harris both deserve praise for steering their sides to within a whisker of the play-off spots.

Millwall look primed to finish in the top six, but Wilder's Blades need a couple of big results to force their way in.

They didn't come much bigger than the 2-1 victory against Tony Pulis and his Boro side in midweek though, where a Lee Evans brace gave them the points.

His first, a sumptuous side-footed volley, lit up Bramall Lane.

With big games come big decisions and Wilder has at least two calls to make ahead of the Lions visit.

Here at FLW, we take a look at two big decisions that he doesn't have long left to make.....

Chelsea loanee Blackman has played most of the season in the sticks for the Blades, 28 times in total. However, his recent sending off against Brentford opened the door for Simon Moore, the holder of the number one jersey.

Moore has conceded five in the three games he's played, three against Barnsley perhaps those that cause the most concern.

Chris Wilder must decide whether to recall Blackman, or stick with Moore. Blackman's red card was bizarre, an act of petulance on both his part and Ryan Woods, but it could have cost his side dearly.

Which way will Wilder go with this massive call?

The experienced Mark Duffy missed out against Middlesbrough, but Chris Wilder is likely to want his experienced midfielder to return to the team if he's fully fit.

If he does, it could mean 24-year old John Lundstram dropping to the bench, but will Wilder want to change a winning team, one that dealt so effectively with Middlesbrough? It's a big call to make and time is ticking away.
