With the English Football League fixtures set to be unveiled tomorrow morning, we take a look at those sides who have been joined QPR, Fulham and Brentford in the Championship.

Today we look at the three sides who've been promoted from League One, Sheffield United, Bolton and Millwall.

Sheffield United

A team who proved to be one of the most attractive sides in the Football League. Whether Chris Wilder's attacking style pays dividends in the Championship remains to be seen, but the evidence suggests that they'll have enough in their tank to pick up some wins along the way, even if they are caught out against some of the league's higher quality teams.

With the likes of Billy Sharp and Ched Evans within the ranks, there are certainly goals in this Sheffield United team and it'll be interested to see how they cope.

Verdict: I think Sheffield United will have enough about them to pick up enough wins to secure survival next season, however they will need to strengthen with some proven Championship signings.

Bolton Wanderers

In stark contrast to League One champions Sheffield United, Bolton ensured promotion based on the foundations of a solid defence. This could be a huge benefit to the Trotters, but they could struggle at the other end, where after all, you need to be able to get goals to win games.

Verdict: A solid defence could make Bolton a difficult proposition for any team in the league, but unless they are able to strengthen at the other end i could see Bolton struggling to win enough games.

Millwall

The Lions showed their experience by keeping their heads through the play-offs in order to defeat Bradford in the final through a Steve Morrison strike. A side with undoubted ability to find the net through Morrison and Lee Gregory, but a question mark will remain over whether the entire squad has enough about it to stay in the division. As you'd expect, the need to ensure the Den remains the true definition of a fortress is essential in order to put opposition players and fans on edge when they arrive in Bermondsey. If they can do this, and pick up regular points along the way, they may just have enough to compete this year.

Verdict: A huge amount of pressure remains on the shoulders of Steve Morrison and Lee Gregory, it's vital the rest of the team are able to step up, or that they can strengthen the squad to ensure they aren't scrapping at the bottom of the league.
