The Blues have drawn Championship new boys Luton Town away in the first round of the Carabao Cup.
The tie will take place at Kenilworth Road in the week starting August 12th, following Town's first home game of the season against Sunderland.
The teams last met in the same competition two seasons ago, also in round one, when the Blues, then in the Championship with the Hatters in League Two, won 2-0, David McGoldrick netting both goals in the Blues' only cup victory in the last three seasons.
Town and the Hatters were also drawn together in the competition on two further occasions.
In November 1987 John Duncan's Blues were beaten 1-0 at Portman Road in the fourth round of what was then known as the Littlewoods Cup with Brian Stein on target. The Hatters went on to win the trophy that season.
Luton were also victorious in a two-legged second round tie between the sides in September 1998, winning the Kenilworth Road match 4-2 - David Johnson and home defender Sol Davis netting for Town and Andrew Fotiadis, Stuart Douglas, Davis at the right end and Marvin Johnson for Luton - after George Burley's Town had won 2-1 at Portman Road when Manu Thetis and James Scowcroft were on the scoresheet for the Blues.
Overall, the Blues have won 12 games (eight in the league) between the sides, Luton 12 (nine) with five (three) having ended in draws.
Tonight's draw took place in the Morrisons supermarket in Colindale, close to Wembley Stadium where the final will eventually take place, and was carried out by John Barnes and Ray Parlour.
Last season the Blues were beaten 4-2 on penalties at Exeter City in round one following a 1-1 draw.
