Harris: Fulham face a mauling in the Lions' Den
Championship: Millwall v Fulham, live, tonight, Sky Sports (KO 7.45)
Fulham have been warned they will sink or swim when their quest for automatic promotion to the Premier League continues at Millwall.
The Cottagers are competing with Cardiff for second place in the Sky Bet Championship and will overtake their chief rivals in the table if they prevail in tonight's London derby, albeit having played two more games.
But their success in the second half of the season has been mirrored by play-off hopefuls Millwall, whose boss Neil Harris believes the venue for the showdown between the league's two form teams is critical.
"The Den can be a hostile environment and an intimidating place to play," Harris, whose side have gone 17 Championship games unbeaten, said.
"Not for my players. My players are going to thrive off it and enjoy it. We have seen a lot of teams struggle over the years. I hope it gives us that added edge to be able to impose ourselves on the game.
"I know when The Den is full and it is rocking we are a very difficult club to stop. Players sink or swim and my players will be swimming. They will be flying.
"It is your home environment and you want it to make your players produce their best. It has certainly done that in the past few years."
Millwall are definitely missing Byron Webster due to a knee problem, but midfielder Ben Thompson could recover from his ankle issue in time.
Fulham have Floyd Ayite and Sheyi Ojo unavailable.
