Millwall boss Neil Harris has asked his players to perform off the back of a "hostile and aggressive atmosphere" when Derby County visit The Den in the Sky Bet Championship on Saturday afternoon.
The Lions return to home soil in the League after a battling 0-0 draw at Blackburn Rovers last Saturday and come up against a Rams side managed by ex-England and Chelsea star Frank Lampard - who is assisted by former Lion Jody Morris.
The boss told millwallfc.co.uk that whilst he is looking forward to meeting up with two old friends, all attentions will be stopping a "possession-based" visiting side.
"First and foremost we look forward to welcome Frank [Lampard] and Jody [Morris] to The Den," he said. "They're two lads that I've come across throughout my lifetime - Frank a long time ago at school and Jody, Livers and I played with him.
"Derby are another club at this level with a huge array of talent. They've had great spending power over the last 18 months and have a huge squad - they could have two or three XI's and still be competitive in The Championship.
"We don't know exactly who we're going to face personnel wise, but we do know what style of play we'll face. They'll be a possession-based team who will dominate the ball and try to frustrate us."
The manager also asked for an atmosphere for his players to feed off as The Lions look to gain a positive result.
"It's a game where we'll focus on what they do and try to stop them playing, but, as ever at The Den, it's about what we do, imposing ourselves on the game. I expect a Millwall occasion, the same as Middlesbrough and the same as nigh on 23 League games last year.
"It'll be a cracking atmosphere. Derby travel well and make noise, so our fans have got to be right at it. It's got to be a hostile and aggressive atmosphere and the players have to perform off of that. We'll look at gaining a positive result."
