Leeds will take on United at Elland Road in the league on Saturday afternoon.
United manager Chris Wilder has already said that Sharp will start for the Blades, as quoted in Leeds Live, and former Leeds winger and manager Gray has outlined the threat that the 33-year-old poses for Marcelo Bielsa’s side.
Gray told LUTV about Sharp: “He has always been a threat against us when he plays against us. He was here, wasn’t he?
"He didn’t have the best of times here. What a goalscorer this boy is! He would love nothing more than to stick the ball in the back of the net at Elland Road.”
Sharp is one of the best players in the Championship, and him starting against Leeds will enhance the Blades’ chances of winning the derby against Leeds.
Former Southampton striker was on the books of Leeds during the 2014-15 season and struggled to make a huge impact at Elland Road.
Sharp has made 28 starts and five substitute appearances in the Championship for the Blades so far this season, scoring 22 goals and providing two assists in the process, according to WhoScored.
Dean Henderson mistake
Meanwhile, Chris Kirkland has suggested that United goalkeeper Dean Henderson will remember the mistake he made against Leeds earlier this season.
Back in December 2018, the 22-year-old goalkeeper - on loan at the Blades from Manchester United - made a bad error late on to hand Leeds a 1-0 win.
Former Sheffield Wednesday goalkeeper Kirkland said on the EFL Matters show on Sky Sports Football on Thursday evening (7pm, March 14, 2019): “This will be on his mind, I am sure, but he won’t do this again.”
