Billy Sharp
Sharp is a real cult hero with the Blades having started his career with them and then returning recently to fire them to the Premier League.
They are his hometown club and his record of 103 goals in 245 games speaks volumes about his importance at Bramall Lane.
Back in the 2011/12 season though, Sharp was helping Saints to secure a return to the top-flight after just one campaign in the second-tier.
His 10 goals in 18 appearances proved vital following an £1.8m move from Doncaster Rovers, but he was never given the chance to prove himself for the club in the Premier League.
