Billy Sharp and Lee Gregory face each other in a pivotal clash as both teams aim for consecutive promotions.

Sheffield United and Millwall have both had remarkable seasons and the fact that they are realistically fighting for play-off spots so late in the season is impressive in itself. However, the fact that they have got so close means that it would be a disappointment for both clubs if they don't finish there, which makes this clash fascinating.

The Lions play the more direct style of the two because possession isn't important to them with the priority being getting the ball into the forward areas through any means necessary. They have a large amount of aerial threats so crossing and set pieces are key ways for them to create chances.

In contrast, the Blades are more versatile because they are happy to have possession if needed, but they focus on stifling the central areas which plays to their strengths in wide areas where they like to work the ball to the byline with overloads before cutting it back.

Sharp and Gregory have both been key in firing their respective sides up the league tables. However, the fact that Sharp has more goals than Gregory, but isn't his sides' top scorer shows a key difference between the sides.

United's scoring is more restricted to the forwards while Millwall spread it around the team, but they are both successful with their methods. Gregory has more of an all-round influence in the final third through his dribbling and key passes. However, Sharp is more prolific with 12 goals in 30 games compared to 10 in 39 for Gregory.

They both play key roles in their teams, but purely as a striker Sharp is better because he scores more from less shots while also having the same amount of assists.
