Rotherham United will be hoping that they can mount a promotion challenge from League One next term.

The Millers were a central figure in a dramatic Championship relegation battle which rumbled on until the closing minutes of the final game of the season when they were sent down after a 1-1 draw with Cardiff City.

Paul Warne is now putting plans in place to strengthen his squad ahead of the new season.

One player who has been linked is Cambridge United's Paul Mullin, but what do we know so far, and is a transfer likely to happen?

We take a look.

What do we know so far?

Reports from The Sun (23rd May, page 59) reported that Rotherham United were plotting a move for the striker.

Mullin enjoyed a wonderful season with Cambridge United in League Two after scoring 33 goals in 50 appearances as he helped the U's to secure automatic promotion to League One.

The 26-year-old is out of contract this summer, but with Bristol Rovers and Plymouth Argyle also said to be keen, it means that Rotherham could have some tough competition to get a deal done.

Is a transfer likely to happen?

While Cambridge United are surely keen to keep hold of the striker, it could prove to be tricky given the amount of competition for his signature.

Rotherham United would surely be an attractive proposition for the 26-year-old due to the fact that they're bound to be challenging for promotion this term, but there are a lot of different factors which will go into Mullin's decision.

That said there's no doubt that Paul Warne will be doing all that he can to tempt the striker to South Yorkshire if he is a player who is so soughtafter.
