The Southampton striker has been linked with a loan move at Bramall Lane.
Sheffield United are shopping for attacking options, with manager Chris Wilder saying that new players should be announced in the next week or two.
Southampton's Sam Gallagher is one of the names that has been linked with a move to the Blades, so here's everything you need to know about the 22-year-old...
Gallagher spent last season in the Championship on loan at Birmingham City, where he scored six goals in 33 appearances for the struggling Blues.
Despite a stop-start season at St Andrew's, Gallagher finished as Birmingham's top league scorer.
The big target man has also spent time at MK Dons and Blackburn Rovers in the previous two seasons, while biding his time for a chance at his parent club.
During his time at Blackburn in 2016/17, he bagged 11 goals in 43 appearances but couldn't stop them from being relegated.
After starting his career at Plymouth Argyle, the 6ft4in powerhouse sealed a move to St Mary's in 2012 and has travelled with the team on their preseason tour in China.
Highly rated by many Southampton fans, he bagged the winner in Southampton's 3-2 victory over Jiangsu Suning on Wednesday.
He is behind Charlie Austin, Shane Long and Manolo Gabbiadini in the pecking order at the Premier League club.
