Forest go into the high-profile clash off the back of successive away wins at Ipswich and Barnsley, but still down towards the wrong end of the table, sitting in 17th spot.
Defender Worrall, who this week has been linked with a host of Premier League sides, says the side must continue to do what they have been in their last two games when they come up against the league leaders.
He told reporters: “Fans and a lot of people think it’s the same old football cliches, ‘We go again’ and everything, but it literally is. Whoever you come up against, it doesn’t really matter, you have just got to try to get those three points.
“It means a bit more that Forest is my team and always will be, and trying to beat the best team in the league is a challenge, but it’s a privilege to be playing against them, so it’s good.”
