United have completed a fourth signing of the week after securing a deal for Scotland international Oli Burke, who joins from West Bromwich Albion for an undisclosed fee.
Following the arrivals of Derby pair Jayden Bogle and Max Lowe, along with Chelsea's Ethan Ampadu on Monday, Chris Wilder has now swooped to bolster his attacking options after cementing a move for Burke, who signs a three-year deal at S2.
As part of the deal, striker Callum Robinson has moved in the opposite direction, also for an undisclosed fee.
On his latest bit of business, the Blades gaffer remarked: "We needed a touch of pace and Oli certainly gives us that. We've been working on it for a few weeks and obviously we wish Callum (Robinson) all the best.
"It's a move that suits all parties and we are delighted to have Oli in the building. He's had a couple of big moves in the past that haven't gone as he'd have hoped, but it's down to us now to give him a kick-start and he's got all the attributes we want and need.
"When you put it on paper at the end of the window and take a sigh, it's been an outstanding summer for us, we will 100% be stronger than when we stepped through the door into the Premier League and that's how it has to be."
The Kirkcaldy-born ace, who can play wide or through the middle, started his career at Nottingham Forest where his early progress earned rave reviews. He made his professional debut aged just 17 back in 2014, and during his first season at senior level he also enjoyed a loan spell at Bradford City.
In the 2015/16 season he made 21 appearances for Forest in all competitions, and after a blistering start to the following campaign, Bundesliga side RB Leipzig had seen enough to part with a reported £13m to bring him to Germany.
In 2017, Burke returned to the UK after signing for West Bromwich Albion in a deal reported to be worth £15m, breaking his own record as the most expensive Scottish footballer. He gained Premier League experience initially, but recently has taken the opportunity to gain experience elsewhere with two notable loan moves.
In January 2019 he joined Scottish giants Celtic making 19 appearances in all competitions as Neil Lennon's side won the title. Last season he moved out to Spain after agreeing a season-long loan with La Liga side Alaves, making 32 appearances.
Burke made his international debut against Denmark in 2016 and netted his first goal for his country against Cyprus in 2019. He was part of the Scotland squad, alongside John Fleck, for the Nations League double header against Israel and Czech Republic earlier this month.
As the start of the season fast approaches that takes United's incomings this summer to a total of six following the arrivals of goalkeepers Wes Foderingham and Aaron Ramsdale, in addition to the aforementioned trio that signed on Monday.
