The west London side have blitzed their way to the top of the league scoring a stunning 79 goals in just 31 matches, and the Posh, who have the joint worst defensive record in the division, will be bracing themselves for an attacking onslaught from Marco Silva's in-form side.
Peterborough are currently 23rd in the table, having won just five times in the league all season, and will be desperate to get some precious points on the table and move out of the relegation zone.
Meanwhile, Posh chairman Darragh MacAnthony has responded to some fan criticism in his role recruiting players, and said: “I’ve told my partners I’ll take a step back from recruitment if that’s what they want. It’s been my thing and if it hasn’t worked I will hold my hand up.
“I've also put to my partners they can buy me out if they want, but I am working with two magnificent, classy guys who immediately try to pick me up when I start talking like that. I’ve always said I’ll know when it’s time to get on the platform and take the train out of here, but this club is not just about the Championship.
“Of course we want to establish ourselves in the division if we can. We have tried, and are trying, very hard to make that happen."
Take a look at the latest news and transfer stories from the second tier, ahead of another busy midweek packed with fixtures:
