Ray Kennedy scored against his former club with nine minutes remaining as Liverpool recovered from a goal down to beat Arsenal 2–1 at Anfield on 7 February 1978. His winner gave Bob Paisley's team a narrow lead in a League Cup semi-final that offered a place in the club's first final in the competition.
Arsenal struck first. Malcolm Macdonald put the visitors ahead in the 13th minute, leaving Liverpool to recover on their own ground before they could think about taking an advantage to Highbury.
David Fairclough had started alongside Kenny Dalglish and Steve Heighway in a side that also included Kennedy, Jimmy Case and Terry McDermott. Fairclough supplied the cross for Dalglish's equaliser in the 26th minute, restoring parity before the interval.
He would also help create the winner. With the score still 1–1 late in the second half, Phil Neal played a free-kick to Fairclough, whose delivery into the goalmouth reached Kennedy. The former Arsenal forward scored Liverpool's second, completing the recovery in front of 44,764 spectators.
Liverpool had turned an early deficit into a lead, but the tie remained close. Arsenal still had a home leg in which to recover, and Kennedy's goal would prove to be the last scored in the semi-final.
At Highbury on 14 February, Liverpool held Arsenal to a 0–0 draw. The 2–1 aggregate victory took them to Wembley to face Nottingham Forest on 18 March.
Dalglish's equaliser and Kennedy's winner had both depended on Fairclough's supply. Between them, the three had provided the goals Liverpool needed; the return leg supplied the clean sheet that made them sufficient.
