Manager Neil Harris praised "hostile" and "aggressive" Millwall following his team's 2-1 Sky Bet Championship victory over Middlesbrough at The Den on Saturday afternoon.
Jed Wallace and George Saville put The Lions into a 2-0 lead in the first-half, but Stewart Downing reduced the arrears midway through the second-half.
Millwall, however, held on for an important win - one that Harris stated saw "desire and determination."
"I think it's clear top teams don't really like coming here this season," he said. "We are what we are as a football club. We're hostile, we're intimidating, we play aggressive football with and without the ball and we play good football as well - you can see that with the first goal in particular.
"The players have got real desire and determination. We haven't got players worth millions of pounds, but I think I have a lot of players growing in reputation at this level because they are very good players. The biggest credit I can give them is that they're a very good team.
"We made a top Middlesbrough side look really ordinary at times today."
The manager also reserved special praise for the spine of his team, including front pair Steve Morison and Lee Gregory.
"I thought Steve was outstanding today, as was Lee. Their work ethic, their link-up play, the way they hold the ball and get us on the counter-attack, the way we defended from the front - I think at times they both took care of four defenders on their own.
"Combinations all over the park were very good. The two centre-halves were outstanding against a very expensive forward line, plus the two boys in midfield, which turned into a three when Shaun Williams came on. Ryan and George were dominant in the middle of the park.
"Middlesbrough dominated the opening part of the game, but the 25 minutes leading up to half-time was as good as any in my time in charge."
