Leicester City's Capital One Cup quarter-final with Manchester City at the King Power Stadium is expected to sell out today.
Tickets went on general sale yesterday morning and only limited numbers are left.
It followed a two-week period in which season-ticket holders could purchase their tickets for the visit of Manuel Pellegrini's Premier League title challengers.
Supporters queued outside the ticket office at the King Power Stadium before the doors opened yesterday morning to ensure they got their tickets to see if Nigel Pearson's men could book their place in the semi-finals. Victory on Tuesday, December 17, would move City a step closer to a first appearance at the new Wembley.
The last time City reached this stage of the competition they overcame Fulham, in 2000, at Filbert Street after extra-time and went on to lift the trophy, with a 2-1 win against Tranmere.
City last faced Man City nearly three years ago in the FA Cup third round at the King Power Stadium.
A 2-2 draw earned City a replay at the Etihad Stadium, where they eventually went down 4-2.
Club ambassador Alan Birchenall is expecting another classic clash.
"It should come as no surprise to anyone really, but what an incredible response from the Leicester City fans," he said.
"You can always rely on them to make the big occasions that little bit more special. To have the game pretty much sold out four weeks in advance is a terrific effort.
"It was a great draw when the two teams came out of the hat, and what a tie it is now to look forward to – one of the leading clubs in Europe at the King Power Stadium in front of a packed house just before Christmas. It's got the makings of a classic."
Meanwhile, a big crowd is expected for City's Championship clash with Ipswich at Portman Road.
City are expected to take more than 1,000 supporters to East Anglia on Saturday, and Town have reported good tickets sales as they have introduced a 'kids for £1' offer for the fixture.
Defender Ritchie De Laet has returned to training during the international break but may not be ready to return in time to face the Tractor Boys.
The Belgian right-back had surgery on an infected cut on his shin, which refused to heal, last month and has not played since the defeat at Doncaster on October 5.
Liam Moore, who has switched to right-back from centre-back in De Laet's absence, is set to deputise again.
Moore is currently with the England Under-21 squad to face San Marino at Shrewsbury tonight.
