A tough season is on the cards for the Millers, with the club limited by their resources. 

After beating Shrewsbury Town in the League One play-off final, the South Yorkshire club find themselves back in the Championship.

With the spend from Championship clubs going up season after season, as they chase the ultimate prize of Premier League football, it becomes increasingly hard for the clubs with less financial prowess to compete.

Despite a brave battle last season, low spending Burton Albion found themselves relegated.

There is a heavy importance on making smart additions due to this financial limitation.

Paul Warne has brought in a duo from Blackpool, in Kyle Vassell and Clark Robertson.

This indicates Warne is looking at a strategy of cherry picking some of the best talents from League One, and giving the opportunity to showcase their talents in the Championship.

Vassell has been at a plethora of clubs in the lower leagues, spending much of his career with Non-League sides, with some spells in Leagues One and Two, notably with Peterborough United.

Vassell looked to really find his feet at Bloomfield Road last season, scoring 11 goals in 29 appearances for the Tangerines.

Rotherham United are taking a risk on Vassell, giving the striker a three year contract and hoping he can make the step up, but it is a risk the club seemingly needs to take.

Clark Robertson is another who has been a key man at Blackpool for the past few seasons.

He has been a major part of their against-all-odds good seasons, in the midst of the controversial ownership of the Oyston family.

The centre back, who began his career in native Scotland with Aberdeen before moving to the Lancashire coast, may be a shrewd piece of business by Warne.

If Warne can get his players playing in a system they are comfortable with, and build a team spirit at the New York Stadium, the Millers may well exceed expectations in the Championship.

The one thing for certain is that Warne and his staff have a lot of hard graft ahead of them, as they face the battle of keeping Rotherham United in the Championship.
