Despite dropping two points against play-off rivals Millwall last time out, Sheffield United still have a good chance of making the top six but they know they need a near faultless end to the season.

Whether they do get a shot at the Premier League or not, it still can't take away from the fact that Chris Wilder and his team have had a fantastic season on their first season back in the Championship.

Clearly, the club are on the up and even if it doesn't happen this year, the focus in 12 months time will be on making sure they are even better and closer to the top six.

To do that, they will need a few new additions and Wilder will know where the Blades are weak.

That in turn, could lead to departures. Here we look at four players who could be off in the summer...

The experienced defender has been superb for the Blades since joining and Wilder will certainly value everything he has done for the club.

However, he hasn't established himself as first choice in the back three this season, spending more time on the bench than he would've liked.

At 32-years old it's hard to see him getting any better and if a new defender arrives in the coming months he may be moved on. It's also something the player might be open too as he will want regular football.

Similarly, Moore won't be wanting to sit on the bench but he has found himself doing a lot of that season with the form of Jamal Blackman.

Wilder clearly prefers the Chelsea loanee, bringing him straight back into the team against Millwall after suspension.

If, as expected, they pursue a deal for Blackman in the summer, it's hard to see Wilder keeping Moore happy as number two. Once again, a move may benefit all parties.

The midfielder is highly unlikely to be at Bramall Lane this summer.

Although Carruthers has made 14 league appearances this season, he hasn't made the squad in recent months after Wilder's January additions pushed him further down the pecking order.

A move seems inevitable in the summer.

Things haven't really gone to plan for Evans since he returned to Sheffield United in the summer.

He has failed to win a place in the team and another who has been hampered by injuries. With a striker likely to be a priority this summer it's hard to see where he fits in.
