IAN Holloway was delighted with the competitive workout his side were given by Stevenage in Saturday's friendly at the Lamex Stadium.
The League Two side were full-blooded in the tackle and challenged for every 50-50 ball as the Lions were put through their paces in hot and sticky conditions.
Midfielder Nicky Bailey required a stitch in his shin after being caught by the studs of Simon Walton in the 2-2 draw, but Holloway had no issue with the ferocity of the game.
He said: "It was fantastic wasn't it? That's what you don't get when you play against yourself.
"We were very disciplined, we looked after ourselves and we didn't lose our rag like we could have done.
"I'm delighted with Nicky because it looked like he was going to lose it but we calmed him down.
"That's how you stand up to a late tackle. Was it meant? I don't think so, Stevenage just wanted to win and that was nice."
Minutes after receiving treatment, Bailey put Millwall ahead with a close-range tap in before Walton's quick-fire double gave Stevenage the lead.
But Jermaine Easter rescued a draw with a well-taken penalty in the 54th minute.
"I was delighted with the first half but our organisation let us down in the second half when a few of the younger lads came on," Holloway added.
"Their lad took two great free kicks but we could have been further ahead by then – Lee Gregory was unlucky with one he lobbed over, normally he scores those.
"I was delighted with the response after we went behind and it was a great bit of skill to get us back in it – it's just a shame we can't give Fred Onyedinma the ball more.
"John Marquis' disallowed goal was very tight but I don't think it was offside. It was a great workout for everyone and a great day.
"It's a shame we can't play more of these competitive games because the police charge extra just because it's Millwall.
"I don't understand it at all – our fans today were magnificent, so what's the issue?"
