On Wednesday 6th January 2020 Manchester City and Manchester United will play yet another semi-final in the League Cup. Unlike the previous semi-finals however this one will be a one-leg affair (due to potential fixture congestion it was decided to take this approach).
The first ever League Cup semi final between the teams – indeed the first ever League Cup tie between them – came during the 1969-70 season. That was the first season when all 92 League clubs entered the competition.

Here is the background to each of the 1969-70 semi-final legs and a report on each game with lineups, attendance details etc.
