Crawley boss Richie Barker knows what is in store when his side head to Peterborough on Saturday.
Barker travelled to London Road to see Tuesday night's Capital One Cup clash with Reading, in which Posh ran out convincing 6-0 winners.
"I thought Wolves on Friday would be up there as one of our toughest games," said Barker.
"But to go up there on Tuesday and watch that - they've really sent out a warning to the rest of the division.
"Peterborough haven't really had to change their team after being relegated which is good management, and they look like a team who have been playing together a long time.
"They were excellent, but we can play as well."
