Sharp has been in negotiations with the club for a number of weeks but now an agreement has been made.
It means the striker will remain with the Blades until beyond his 35th birthday. It’s likely Sharp will end his career at Bramall Lane.
This will be a timely boost for United as they enter the final stages of their push for promotion to the Premier League.
Sharp has scored 22 Championship goals already this season and as a local boy and captain, is also the talisman of the team.
Sharp can prove doubters wrong
The 33-year-old has had to prove people wrong throughout his career. Struggling to make an impact at the Blades initially after progressing from their academy, Sharp dropped into League One.
Some doubted whether the forward was cut out for the Championship. 30 goals in 62 league matches for Doncaster Rovers between 2009 and 2011 put an end to those thoughts.
Later, with Southampton, it was doubted if Sharp could make it in the Premier League. He was given two games at top flight level before being loaned to Nottingham Forest.
When Sharp rejoined United, then in League One, in 2015 it was thought his career was beginning to wrap up. In the three-and-a-half years since the skipper has netted 86 times in the league.
Once again enjoying a prolific season in front of goal in 2018/19, Sharp could well fire Chris Wilder’s men to the Premier League for the first time since 2007.
And you can bet that there will be those that say that he is too old or simply not good enough for that division. It should come as no surprise to Blades fans if Sharp continued to prove the doubters wrong yet again.
