Northampton will bid to claim another major scalp on Tuesday night when they travel to QPR in the first round of the Carabao Cup.
The Cobblers knocked out Liverpool on penalties in the third round at Anfield seven years ago and repeated the feat against West Brom in round two last season before losing to eventual winners Manchester United.
"We'll go there to impose ourselves and try and put our own style of play on the game, to try and cause an upset and get through to the next round," Cobblers boss Justin Edinburgh told the Sky Bet League One club's official website.
"We know what lies ahead. If we can get a good victory in this round and cause an upset then we could get a big draw.
"We can't look beyond QPR, who had a fantastic result on Saturday at home, but we certainly go there looking to cause an upset."
A total of 29 first-round ties take place on Tuesday night and another five 24 hours later as English football's second biggest knockout tournament gets under way for the first time since being rebranded under new sponsors.
