IAN Holloway praised the performance of 18-year-old debutant Sid Nelson after Millwall were beaten 2-0 by league leaders Bournemouth.
Nelson, a product of the club's youth academy, made his first Lions appearance against the Cherries on Sunday and won the man of the match award with a battling display.
But he couldn't prevent Millwall from slipping to their fourth straight home defeat as goals from Yann Kermorgant and Harry Arter gave the visitors three points.
"After what happened to us the other day at Norwich, I didn't know what I was going to see out there," Holloway said afterwards.
"I saw people give up at Norwich and that was shocking, so I couldn't put up with that. I decided to shake things up, put a kid into the defence and Sid was excellent.
"We had to have some sort of reaction and I got it, so I'm not too unhappy with the players today.
"Sid has given me another option at the back. He was fantastic. He's only 18 years-old. Brilliant – that's all I can say. That's Millwall for you – his whole family are fans.
"He gave everything and didn't stop. I told him earlier today that he'd be starting. We had to walk through things yesterday because none of the ones who played at Norwich could train.
"Sid was my man of the match."
Kermorgant opened the scoring from the penalty spot after Lee Martin's trip on Charlie Daniels.
But the Lions felt Martin's challenge was made outside the box.
"I expected a free kick to be given, not a penalty," Holloway said. "If you watch it back, I couldn't believe how quickly the referee blew the whistle.
"You've got to be 100 percent sure and to be honest he's 200 percent wrong, because it was outside the box. But did we need to make the tackle? No."
Shaun Williams was sent off in the closing stages after tangling with striker Callum Wilson and Holloway said the midfielder's conduct was "unforgivable".
"It was ridiculous," he added. "Shaun was wronged – he was picked up off the floor and thrown over. Willo had to stay down because maybe their man would've been in trouble.
"He shouldn't have retaliated – he was asking for trouble. That's not the way to please our crowd. I've told Willo that's ridiculous and I'm not accepting that.
"He can't respond like that."
