Steve Morison believes Millwall's win over Leeds United has highlighted the unpredictable nature of the Sky Bet Championship.
The League leaders had no answer for a Millwall performance that was fluid and incisive in attack, and calm and measured at the back.
The Whites entered the match as strong favourites, having scored nine goals over their previous three matches, but didn't muster a single shot on target in front of almost 17,000 vocal fans at The Den.
"It proved that anyone can beat anyone on their day," the Lions striker told millwallfc.co.uk
"It's a bit soon for anyone to be saying "this team will be relegated or that team will win the league" because it is still early days. We showed that a top of the table team can get beaten by a team in the bottom half of the table - quite comfortably too.
"We are a good team and The Den is a tough place to come. When we play like we did and if the other team doesn't fancy the scrap with us then they will come undone. That's what happened to Leeds.
"The fans make it as hostile as possible for the other team. We have a fantastic following and they helped us a lot. I have no doubt they'll continue to help us in the future."
In the absence of usual strike partner Lee Gregory, Fred Onyedinma led the line with intent alongside Morison.
"When he turns up and plays like he did against Leeds - no one can get near him. He needs to do it consistantly and that's what he needs to work on. He's young and he has another two games [While Lee Gregory serves a suspension] to nail his place down in the team."
