Jim Bentley says his side will be giving their all to provide a shock in Tuesday's EFL Cup at Rotherham.
The Millers will go into the game as favourites but Bentley says there is no reason why the Shrimps cannot defy the odds in a competition that they done well on in past seasons.
He said: "It could have been an easier draw I must admit.
"They are a Championship club and a big club but it is always nice to pit your wits against a aide higher up the pyramid and we have shown in the past that we can beat sides further up the levels than ourselves.
"We have a decent record in the competition so we will go there, give it our all and do our best to get into the next round.
"We know we have to improve on Saturday when we went down at Grimsby. We have got good players but they are young and learning all the time and this will be a great test for them.''
