Smart summer rebuild pivotal to Blades' successpublished at 13:41 6 March

You won't see many cleaner strikes than Tyrese Campbell's winner for Sheffield United at QPR.
It was the 25-year-old forward's seventh goal of the season since switching from Stoke City last summer, and it was due, after a purple patch of six goals in eight matches before injury stuck in December.
Free-transfer Campbell is just one example of the Blades' excellent pre-season recruitment drive that has propelled Chris Wilder's men into the Championship's automatic promotion places.
There was lots of talk in January about the £10 million plus fee spent on Tom Cannon but that was only possible after the club's protracted takeover by American investment group COH Sports.
There's no doubt United have one of the bigger budgets in the division, having just come down from the Premier League, but the build up to this campaign was dominated by those takeover delays as modern legends departed in a big turnover of players, following one of the worst campaigns in top flight history.
It meant Wilder had to wheel and deal for a limited squad with shrewd sales allowing the club to wisely spend small seven-figure sums on goalkeeper Michael Cooper, left-back Harrison Burrows and international striker Kieffer Moore.
Campbell was joined on a free by Callum O'Hare – both have been excellent – while loanees Harry Souttar, Alfie Gilchrist and Jesurun Rak-Saki have all played key roles this season.
If the Blades do achieve an immediate return to the Premier League, a significant amount of credit should be placed on last summer's rebuild.
