Neil Harris admitted he came back down to earth with a bump after watching FA Cup giant-killers Millwall stumble to a goalless draw with Rotherham.

Just seven days after the Lions produced one of their greatest ever wins against Everton in the FA Cup fourth round, they struggled to get anything going against a Rotherham side fighting with them towards the bottom of the Sky Bet Championship table.

And it was the Millers who perhaps should have won, with Michael Smith missing two fine chances in the second half, although Harris was adamant Richard Wood should have been sent off for a tackle on Jordan Archer.

Harris said: "I've seen it back. From what I saw it's a horrendous challenge. The lad jumps over Shaun Williams, two-footed, to challenge Jordan Archer. Whether the ball is loose or not is irrelevant. It's a nasty challenge.

"The referee's seen the challenge but thinks the ball was there. If he's seen the challenge, gives a card for the challenge, it has to be a red one.

"I think most people came to the ground today expecting after the Lord Mayor's Show. I'm sure that would have been part of their team-talk after the performance and atmosphere last week.

"But I thought first half we played some really good stuff against a very difficult opponent to play against. First half I was relatively pleased and thought we'd go on and boss the game.

"In the second half we were poor, we weren't brave enough with the ball. I thought we could have controlled possession a little bit better than we did, we never really got sustained pressure on their goal, and that's the disappointment for me.

"I'd rather look at the positives, it's 11 points from six games, rather than look at the performance in the second half and the chance we missed at the end."

Millwall remain four points ahead of Rotherham in the table and the Yorkshire side are just a point above the drop zone.

Manager Paul Warne was satisfied with a point, after watching Millwall's Lee Gregory miss a sitter from 10 yards late on.

"I think if they hadn't had that chance in the last few seconds I'd probably be a little bit disappointed, but I'll be honest a draw's probably a fair result for both teams," he said.

"The first half was poor, devoid of any clear-cut chances. The second half was a lot better.

"Both teams, the players on the pitch give everything they have for both managers, in that respect it was good. On clear-cut chances, we might have edged it, but unfortunately, we didn't take them.

"But to come here, against the in-form side in the Championship, it's never an easy place to come and Millwall's home record is similar to ours, so to come away with a point, I'm pretty pleased.

"We're not bad away from home, and we create chances. At the crucial moments in games, we let ourselves down in one box, and don't take our chances in the other box.

"In fairness to the fans who kindly come to support us every away game, they'll probably go naked in the streets if we actually do get an away win, and nobody wants to see that, especially in this weather!"
