Sheffield United will be looking to continue their fine run of form this weekend as Championship action resumes.

This weekend marks the beginning of a very busy period, comprising the festive schedule as well, as we should see which sides are going to challenge come the end of the campaign.

This might just be the biggest test for the Blades this season, then, and so we've taken a look at whether they have enough strength in depth to cope...

Sam Rourke

Let's be honest, this is a worry for Wilder.

The Blades have one of the most consistent, organised starting elevens in the second tier, but on the bench it could be argued there is a lack of depth.

Yes, there are the likes of Billy Sharp and David Brooks to come off the bench, but if there was an injury to someone like John Fleck, do they really have an adequate replacement?

Alfie Burns

For me, this will be the biggest test Sheffield United will face this season.

Fixtures come thick and fast over Christmas, and how Wilder rotates his squad will be key.

Sheffield United’s starting XI doesn’t change too much, which could prove to be a problem over Christmas, as some of the club’s fringe players are yet to be tested properly.

A key period, where we will learn a lot more about the Blades’ promotion credentials.

Chris Gallagher

Yes, I think they have.

Like every team in the league they have one or two players that are more important than most, but they have reasonable depth.

For example, Richard Stearman is coming back from injury and is good at this level, whilst Clayton Donaldson is an experienced player up top who has only played four games.

They might be a body short in midfield, but I think every club would want that one extra player.

Adam Simeoni

It is a concern. Game after game will take its toll on the squad, which is mainly comprised of players from last year's League One title success.

The Blades have done magnificently so far, and if they can come through the testing festive period then they must be considered serious contenders for promotion. It will be a struggle, however.
