IAN Holloway heaped praise on Brentford after their 3-2 win at The Den.
The Lions boss predicted that the Bees would be his side's toughest test of the season so and his pre-game prophecy proved accurate as they claimed a deserved victory.
It took a Danny Shittu own goal to settle matters but the Bees were good value for the three points after they bossed proceedings for long spells.
Speaking afterwards, Holloway admitted that Mark Warburton's side, who were inspired by two-goal striker Andre Gray, were worthy winners.
"Fair play to Brentford," he said. "I knew how good they were by watching them. Mark is three or four years ahead of me in what he wants to do.
"I'm giving all the credit to Mark because he must have been doing a job above their last manager and setting things up."
Warburton has been at Brentford since 2011 and worked as a first team coach and then sporting director before taking the first-team reins in December 2013.
"Their players knew exactly how, who and when to close," Holloway said. "They lost their best player in Jonathan Douglas but they came here and picked our pockets.
"Brentford know they've been in a game but everybody should start looking at the fantastic job they're doing.
"I'm a little bit jealous because their front six knew how to press and they did that without Douglas, who's their best organiser.
"I think they are the only team that have deserved to beat us. We could've got a draw but they are ahead of us, so well done to them.
"I know what Mark knows and it's very good. He's put that in place from top to bottom because the knowledge of their players was excellent.
"Watford have got more expensive players but Brentford's structure and way of doing things is as good as anybody's at the minute.
"Brentford have pace and a young, fresh, hungry squad – big time.
"I've got to eventually change the balance of that here."
Millwall looked like getting something from the game after they recovered from 2-0 down to equalise, with Lee Gregory and Alan Dunne scoring in quick succession.
But Shittu then turned Gray's cross into his own net to restore the Bees' lead.
Holloway was unhappy with the organisation of his players – and revealed his regret at dropping Scott McDonald from the starting XI.
"Without Scott we didn't know how to press or how to close," he said.
"We really missed McDonald. He's been our best player this season but I wanted to give him a rest because we scored two without him the other day.
"He'd played every minute of every game but boy oh boy did I rue the decision to leave him out. He sets the tone of our closing and pressing."
Assessing the match overall, Holloway added: "We should've stuck to our game plan and we didn't have it right from the first couple of minutes.
"I didn't want their left centre half getting the ball, we wanted to channel it to their left back and we worked on it, but our two wide men started on the wrong side.
"I don't understand why my team didn't organise that.
"The mistake for the first goal was not Shaun Williams' pass, the mistake was not making a better angle for a pass because we knew they'd press.
"For the second, we rolled it into an area where they are very good at pressing and Magaye Gueye gives it away.
"We looked stronger at set plays but we should never have let the third goal in. A gap between Shittu and Mark Beevers let them in. I was gutted with that.
"When we went from back to front and put them under pressure, we looked really good.
"I've got a load of work to do. I might have to look at changing shape and playing a different way to give our boys some confidence."
Holloway also addressed the fact that he made four changes to his line up.
"I've got a massive problem because not all of my boys are as fit as they need to be, in my opinion," he explained.
"Mathias Ranegie isn't fit after a hamstring tear and our fans are slaughtering him but I don't see him not trying – I see him as not fit enough yet.
"If I'd tried the same team over and over again I'd have had four or five injuries by the end of today, I can tell you that now.
"So do me a favour, I've been a manager for 18 years. I'm not deliberately chopping and changing – I don't want to do that."
