After securing a magnificent return to the Premier League, Sheffield United fans must be absolutely euphoric heading into the summer.

The Blades have surprised plenty of people this season, and after being at loggerheads with Leeds United in pursuit of the second automatic promotion place all season long, Chris Wilder's men have now got the better of their local rivals.

Now, despite a trip to Stoke on the horizon, Wilder will surely be casting one eye on the summer window, as he looks to sustain his side's place in the top-flight.

Wilder is a man who has recruited wisely at Bramall Lane over the last couple of years - he has hardly broke the bank since taking the reins of the Yorkshire club, with the likes of David McGoldrick arriving on a free transfer.

Of course, the Blades will need to spend a considerable amount if they are to compete next season, and with that being said, we take a look at three signings that United could realistically make in the summer...

Dean Henderson

This is the signing that every single Blades fan will be urging the club to make in the summer.

After such an impressive loan spell with United, Henderson is more than ready to make the step-up to Premier League football.

He has already insisted that he wants to stay at Bramall Lane, and with talks believed to be happening this week, this addition looks inevitable.

Jermain Defoe

Defoe was linked with a move to Bramall Lane in January, but ultimately opted to sign for Steven Gerrard's Rangers instead.

The experienced forward has since scored seven goals in eight league starts for the Glasgow club, which shows that he can still score goals despite approaching the age of 37.

The veteran front-man would provide much needed top-flight knowhow to what is already an experienced front-line. He would jump at the chance of playing in the Premier League on a regular basis, for potentially one last time.

Nick Powell

Powell has been influential for Wigan Athletic once again this season, but is currently facing an uncertain future at the DW Stadium.

The playmaker, who has scored eight goals and produced six assists for the Latics this term, is out of contract with the club at the end of the season, with the likes of Sheffield Wednesday and Norwich reportedly vying for his signature.

If Wilder is to stick with his trusted 5-3-2 formation next season, then Mark Duffy simply needs competition, and Powell would bring that in abundance.
