Chesterfield v Rotherham United: Young loan pairing bring cool heads to Millers' promotion bid

The pair, who joined the club on loan last weekend, have made only nine senior appearances between them but Moore believes that could be an advantage rather than a problem over the next few weeks.

"Young lads do not freeze, they are not bothered about crowds," he said. "The problem comes with experienced players when the crowd starts getting onto them.

"We have seen that this year at the Don Valley. When things don't work out, the crowd gets on their backs and I know one or two players cannot cope with it."

Left-back Gunning, 20, keeps his place in the side tonight while winger Marshall, 20, may again have to settle for a place on the bench.

Despite the rivalry that exists between the two clubs, Moore has a great relationship with Chesterfield manager John Sheridan and his assistant Tommy Wright, who took over at Oldham Athletic four years ago when he vacated the manager's job at Boundary Park.

"They are good people and they want to play football the right way," Moore said. "But this could be the last time we play Chesterfield at Saltergate and it would be nice to send them off with a bee in their bonnets!"

Moore feels Sheridan and Wright will steer the Spireites, currently eighth, into this season's League Two play-offs but says the Millers' sights are fixed firmly on a top-three spot and automatic promotion.

Although the Millers have dropped to fourth in the table, three points adrift of third placed Bury, they have three games in hand after six consecutive postponements during the cold snap.
