Bristol City manager Lee Johnson expects his players to stand up to the challenge of taking on Manchester United in the quarter-finals of the League Cup.
The Robins have accounted for three Premier League sides on their way to the last eight, knocking out Watford, Stoke City and Crystal Palace.
However, Johnson believes that United will represent another step up in class for his squad, who he knows will have to be at the very top of their game to stand a chance of completing a fourth upset.
He told the Evening Post: "It's a big game, it's a fantastic game - when Manchester United come to town it's a huge game and it's been a while since this club have had a day like this.
"We want to win it, but it is going to be difficult because they are going to have a world-class XI whoever they put out.
"It's a big challenge to see if we can cope with Premier League football. The players can't give an inch because world-class players will take it.
"We've got a group that is very hungry to prove how good they are."
City head into the showdown with United on Wednesday evening in fine fettle, having won their last four Championship games to lie third in the table, behind leaders Wolves and Cardiff City.
The Robins can be backed at 10/3 to reach the League Cup semi-finals, with the Ashton Gate hosts 40/1 to triumph after extra-time and 22/1 to prevail after a penalty shootout.
