Coventry City's new Manager Aidy Boothroyd is warning his players to expect their toughest test of the npower Championship season so far when they travel to face a Millwall side he likens to "a horrible rash."
Having seen his previous club Colchester United lose twice to the Lions in League 1 last term, which Kenny Jackett's team ended with promotion via the Play-Offs, Boothroyd knows more than most Championship managers about his new side's Saturday opponents at the New Den.
And he has every respect for a team that he reckons will be a force this season. "Millwall are like a horrible rash - and I mean that as a compliment," said Boothroyd, whose side have made a good start to the campaign with two wins and a draw from their three League games to date.
"They're absolutely all over you," added the Sky Blues boss. "They're a fantastic pressing team, so they'll put us in positions we don't want to be in and look to feed off any mistakes we make.
"The New Den is not a nice place to go - if you think you can go there and be pretty and play the ball around, you'll get yourselves in trouble. This is not a game for the faint-hearted, it's for tough men to stand up to what Millwall have got.
"They're a good team who've done really well under Kenny. I was impressed with them in League 1 last season and I think they'll be the surprise package in the Championship this year."
Jackett's men made an excellent start to the new campaign, winning their first two League matches and scoring seven goals in the process. But they then lost 3-1 at Leeds United - like themselves newly promoted - last Saturday.
The Sky Blues have meanwhile collected seven points from a possible nine without, says Boothroyd, playing to the standards he is demanding as he looks to produce a side that can challenge for promotion to the Premier League.
The Manager said: "We're a bit of a stuttering car at the moment. We've probably got the wrong fuel in the tank, but we can sort that out and play some good stuff and carry on getting good results.
"You don't build momentum over two or three games, you do it over 15 or 20. And after grinding out some early results, going to Millwall is our next step - and I couldn't have wished for a better test at this stage of the season."
