REACTION: "On another day, we might have scored more," says Warne after Iron win

An Warne, whose side sit in fifth spot in the League One table, was pleased with his side's second half performance.
He said: "I'm really pleased.
"I thought it was a really good game against two in-form teams.
"I knew if we could compete against Scunthorpe then we know we're taking good strides forwards.
"I'm really pleased with how we played. It wasn't a game of many chances first half. We took our first goal well from a routine.
"In the second half I thought we more than matched them and we were the stronger team.
"On another day we might have scored more."
